Fa Zheng

Fa Zheng's ancestral home was in Mei County (郿縣), Youfufeng Commandery (右扶風郡), which is in present-day Mei County, Shaanxi. His ancestor was Tian Fazhang, who is historically known as King Xiang of the Qi state in the Warring States period. Tian Fazhang's descendants changed their family name from "Tian" to "Fa" after the fall of Qi in 221 BCE.^[1]

Fa Zheng's great-grandfather, Fa Xiong, served as the Administrator (太守) of Nan Commandery (南郡; around present-day Jingzhou, Hubei) during the reign of Emperor An in the Eastern Han dynasty. Fa Zheng's grandfather, Fa Zhen, was a reclusive scholar known for his lofty character; despite being a learned scholar, he led a humble life and repeatedly rejected offers to serve in the government.^{[Sanguozhi 2]} Fa Zheng's father, Fa Yan (法衍), whose courtesy name was Jimou (季謀), also served as a government official and held the positions of an assistant to the Excellency over the Masses (司徒) and the Minister of Justice (廷尉).^{[Sanguozhi zhu 1]}

In the early Jian'an era (196–220) of the reign of Emperor Xian, when famines broke out, Fa Zheng and his friend Meng Da travelled to Yi Province (covering present-day Sichuan and Chongqing) to join the provincial governor, Liu Zhang. Although Fa Zheng served as the Prefect (令) of Xindu County (新都縣) and later as a Colonel Who Advises the Army (軍議校尉) under Liu Zhang. Since he didn't have any connection to local clans and was defamed by other refugees from Youfufeng, who had also moved to Yi Province. He couldn't realize his ambitions. He maintained a close friendship with his colleague Zhang Song, who shared the same views as him about Liu Zhang being an incompetent and incapable governor.^{[Sanguozhi 3]}

In 208,^[2] Zhang Song travelled to Jing Province (covering present-day Hubei and Hunan) to meet the warlord Cao Cao, who controlled the Han central government and the figurehead Emperor Xian. After returning to Yi Province, Zhang Song advised Liu Zhang to break ties with Cao Cao and build friendly relations with another warlord, Liu Bei. When Zhang Song recommended Fa Zheng to be Liu Zhang's representative to meet Liu Bei, Fa initially refused to accept the task but eventually relented. When Fa Zheng returned from his mission, he told Zhang Song that Liu Bei had grand ambitions and persuaded Zhang to follow him to serve Liu Bei. They wanted to help him secure Yi province but did not have the occasion to do so.^{[Sanguozhi 4]}

Their opportunity came in 211,^[3] when Liu Zhang became fearful upon receiving news that Cao Cao was planning to attack the warlord Zhang Lu in Hanzhong Commandery. As Hanzhong Commandery was located strategically at the northern route leading into Yi Province, Liu Zhang would be in great peril if Hanzhong fell into Cao Cao's hands. Zhang Song proposed to Liu Zhang to invite Liu Bei to Yi Province to assist them in countering the threat posed by Cao Cao. Liu Zhang agreed and sent Fa Zheng as his envoy to contact Liu Bei. When Fa Zheng met Liu Bei, he secretly told him, "General, with your brilliance, you can overcome our incompetent and weak Governor Liu. Zhang Song, as a trusted adviser (of Liu Zhang), will serve as your spy. Upon acquiring Yi Province's wealth and resources, and having its natural barriers as protection, you can easily realise your grand ambitions."^{[Sanguozhi 5]} Fa Zheng also saw Liu Bei's marital problems and advised him to have Lady Sun sent back to Wu.^[4] Liu Bei accepted Fa Zheng's former advice and led his forces into Yi Province, where he met Liu Zhang at Fu County (涪縣; present-day Fucheng District, Mianyang, Sichuan). Liu Bei then led his troops north to Jiameng (葭萌; located about 20 km northeast of present-day Jiange County, Sichuan) before turning south to attack Liu Zhang later.^{[Sanguozhi 6]}

Upon receiving news of Liu Bei's attack, Zheng Du (鄭度), an assistant officer from Guanghan Commandery (廣漢郡; around present-day Guanghan, Sichuan)^{[Sanguozhi zhu 2]} serving under Liu Zhang, pointed out to his lord that Liu Bei's army lacked supplies and was composed of newly recruited soldiers who might not be loyal to him. He suggested that Liu Zhang adopt a scorched earth policy against Liu Bei by forcing the residents of Baxi (巴西) and Zitong (梓潼) commanderies to relocate elsewhere and destroy all the granaries and supply depots in the commanderies, and then fortify their defences while avoiding direct conflict with Liu Bei. He claimed that if this strategy was implemented, Liu Bei would run out of supplies within 100 days and retreat, and then Liu Zhang could attack him while he was retreating. Liu Bei felt frustrated when he heard about Zheng Du's plan and consulted Fa Zheng about it. Fa Zheng predicted that Liu Zhang would not heed Zheng Du's suggestion and was proven right: In response to Zheng Du's plan, Liu Zhang not only rejected it on the grounds that it would cause disturbance to the people, but also dismissed Zheng from office.^{[Sanguozhi 7]}

In 214,^[5] when Liu Bei's army surrounded Luocheng (雒城), one of Liu Zhang's strongholds, Fa Zheng wrote a long letter to his former lord, pointing out that Liu Zhang was already in a highly disadvantageous position and urging him to give up resistance and surrender to Liu Bei.^{[Sanguozhi 8]}

Fa Zheng's letter was written as such:

"I am of the sort that lack talent yet I completed the alliance objective and later came to disobey you. Now I am afraid that your subjects would not comprehend my true reasons hence putting all the blame on myself however I can be mocked by others yet even with their contempt I would still strive to accomplish the mission I was given faithful to my path. I feared that your lordship would trust those baseless rumors therefore I didn't dare to send letter but now when I look back to how I was treated and thinking of the future, I believe It's not too late. Therefore I will admit everything of my heart, from the beginning to the end, from the earliest to the latest moment. I never hide my feelings and even if I would sometimes not do my utmost, I never hide secret plans but my devotion wasn't acknowledged and now we are in this situation.^{[Sanguozhi 9]}

At this moment, the affairs of the state are of utmost importance and danger is near yet even if I serve another and my words can easily be hated however may what is left of my loyalty to you be used to share my sentiment on the situation. Wise General, I know well the sentiment of your heart and It is to not lose your good relation with the General of the Left^[b] but if we are in this situation is because of your subjects do not understand the way to follow and serve heroes, advocating that one can violate trust and turn his on his vows and instead change his views such as the sun and moon shift looking to only please your ears and eyes with their flattery and fawn therefore cannot plan with thoughtful calculation for the future of the state. The incident already happened therefore they do not judge strength and weakness thinking that the General of the Left's army is isolated far from home with no provisions or grain stored and want to avoid confrontation and just wait for days behind their walls locked together. However when we marched from the pass to here, all of them have been defeated, each of the stronghold and division garrisons have fallen and have been conquered. Even if there are ten thousand troops below Luo castle, they are all weak soldiers and generals of defeated armies. If you thought of fighting a decisive battle then the strength of your troops and generals would be no match. What your strategists wanted to do was to outlast our provisions however now those strongholds have fallen and grain and rice is gathered in great numbers while your own territory Wise General is daily lost and the common people suffer. In that situation, your enemy forces increase and your own supporters grow distant and few. Therefore I have considered those conditions and can say with certainty that you will be defeated first and should not think that you can outlast us. You can try in vain to defend against us but cannot last against us.^{[Sanguozhi 10]}

While I'm writing this letter, Zhang Yide's army of tens of thousands has already conquered Badong, entered Qianwei’s borders, with his divisions pacifying Zizhōng and Deyang as they invade by three different roads then how would you resist this? Wise General, surely your strategists believe that this army is far from home with no provisions, their food supply lines being difficult to keep and their troops few with no followers. However the roads of Jing province are connected and their armies increase by tenfolds also General of Chariots and Cavalry^[c] sends his younger brother with Li Yi, Gan Ning and others to follow after. Now if you want to compare with our lord's strength then looking at the one with the most territory. Now our side has Badong, Guanghan, Qianwei so over half has already been conquered while the important commandery of Baxi will also soon fall Wise General. At the moment, It can be seen that the whole of Yi province relies only on Shu (commandery), but this province is already defeated and ruined; thow thirds of the province are already lost, officials and common people are impoverished and those with rebellious intent against you are eight out of ten households; If the enemy is distant then the common people cannot endure your conscription while if the enemy is near then they would soon change their allegiance. Just for example, what happened during the conquest of Guanghan’s various counties. Moreover Yufu and Guantou are the gateway who can determine the success or ruin of Yi province and now those gates are open, your strongest cities have fallen and your various armies have been defeated, your soldiers and Generals are weakened while your enemy is several steps in advance and already the province’s heart and guts while you await and defend in Chengdu and Luo and whether you would succeed or fail can already clearly be seen.^{[Sanguozhi 11]}

This is only the big picture of what is happening at the moment, the rest is more complex and would be difficult to explain everything. If someone as lowly as me can however comprehend that this situation is doomed and cannot succeed then all the more obvious to the talented ministers in your court Wise General, how they would not understand that that this situation is doomed? From dawn they use flattery and cheat your favour, wishing to keep good appearance's while not thinking of the future, none can devote all of their energy to a long term plan. If danger is near then all of them would first and foremost save their own skins, would strive to help their own families, switch their allegiances back and forth and would be very different of their current composure, not sacrifice themselves for you Wise General however It would be your honored household that would be victim of the disaster they fear. Even if I am already branded as a disloyal man, my heart keep me from turning back against your holiness’s virtue. Only when I look back at my separate mission, I am truly sad that I had to leave you behind. It is the same for the General of the Left and truly he has no unkind intentions. Sincerely, I truly believe that you can still change your plans and then would be able to save your honored household from misfortune."^{[Sanguozhi 12]}

Later that year, when Liu Bei's forces was besieging Yi Province's capital Chengdu, Xu Jing, a commandery Administrator serving under Liu Zhang, planned to surrender and defect to Liu Bei, but his plan was leaked out and hence aborted. Liu Zhang felt that he was already at the brink of destruction so he did not punish Xu Jing. He eventually surrendered and relinquished his control of Yi Province to Liu Bei. After taking over Yi Province, Liu Bei treated Xu Jing coldly because he felt that Xu was a disloyal person. Fa Zheng advised him, "Xu Jing is someone with an exaggerated reputation. However, my lord, you've recently built your foundation and you can't possibly explain the facts to everyone. Xu Jing's name is already well known throughout the Empire. If you don't treat him respectfully, others might think that you're belittling talented and virtuous people. You should honour and respect him, and make this known to everyone, just like how the King of Yan treated Guo Wei (郭隗)." Liu Bei followed Fa Zheng's advice and treated Xu Jing generously.^{[Sanguozhi 13]}

Sun Sheng criticizes Fa Zheng for his advice and the comparison between Guo Wei and Xu Jing :

"One of the most important path of statecraft is to respect the worthies while rewarding virtue and visiting the tombs and gates of past rulers following this example. Hence one must seek after those exceptional and profound of high righteousness reigning over their time, only then can one overlook the land and mixed with the multitude. If this is not such a man then this way shouldn't be followed. Xu Jing while in the household of his kinsman^[d] was not devoted, was put in charge where he didn't belong and when in face of danger was quick to change his heart, his safety was what matters most. How could after that he should be given favor to encourage others? In that case, the favor given to the superficial and false is taken from the worthies unfairly taking their merits then how with what courtesy would they be treated with? Fa Zheng's method just confuse people and detach from the noble and esteemed even give the example of Guo Wei wronging natural human relations."^{[Sanguozhi zhu 3]}

Pei Songzhi completely disagrees with Sun Sheng's opinion:

"Your servant believes that though Guo Wei was not worthy, he received favor for his ability in planning. Moreover, Wenxiu^[e] already had a reputation through the whole empire as an outstanding and great individual even if he made mistakes in the latter years, yet the matter was not as simple. If such a man wasn't treated with respect, how could it not be confused by the people near and far? Fa Zheng's comparison between Xu Jing and Guo Wei wasn't bad, but Sun Sheng made matters complicated by citing honoring tombs and visiting gates; how pedantic! If he was right, then even King Zhao of Yan would be in the wrong; how could the blame be solely on Old Liu (Liu Bei)? As for non-devotion to his kinsman, the fault was with Zijiang.^[f] Just looking at the discussion of Jiang Ji, one can understand that it wasn't Wenxiu's fault. Also, Sun Sheng mocked him for being appointed where he didn't belong; this refers to his service to Dong Zhuo. When Zhuo first gained control of the government, he recruited all the worthies and talented, among those who received rank and office all were awe-inspiring like this. Wenxiu was already an official before Zhuo arrived. Later, he was promoted as Palace Deputy and accepted it. If this should be considered as disparaged, then Xun Shuang and Chen Ji should also be rejected in their times."^{[Sanguozhi zhu 4]}

Liu Bei appointed Fa Zheng as the Administrator (太守) of Shu Commandery (蜀郡) and General Who Spreads Martial Might (揚武將軍). Fa Zheng oversaw administrative affairs in the vicinity of Yi Province's capital Chengdu. While Zhuge Liang was promoted to administer internal affairs, Fa Zheng served as Liu Bei's chief adviser.^{[Sanguozhi 14][Sanguozhi 15]}

Following Liu Bei's victory over Liu Zhang, his subordinates urged him to take for wife Liu Mao's widow. However Liu Bei refused on the basics that he and Liu Mao were of the same family. Fa Zheng then to convince him said: "In the ancient times, lady Huai Ying first married the Duke Huai of Jin and later married his own brother, the Duke Wen of Jin. If the marriage of a widow between brothers happened by the past then why not for you and Liu Mao who are not close kinsman?" Liu Bei agreed with him and married Lady Wu.^[6]

During this period of time, Fa Zheng repaid all of his previous debts, good or bad. He would not forget those who showed him even a little kindness but also abused his power by taking revenge against those who offended him before. And by killing those who harmed him without the legal authority. Someone approached Zhuge Liang, another of Liu Bei's key advisers, and urged him to restrict Fa Zheng's influence by advising their lord to take action against him. However, Zhuge Liang replied, "When our lord was in Gong'an, he was wary of Cao Cao's influence in the north and fearful of Sun Quan's presence in the east. Even in home territory he was afraid that Lady Sun might stir up trouble. He was in such a difficult situation at the time that he could neither advance nor retreat. Fa Xiaozhi supported and helped him so much that he became his own wings (翼),^[g] such that he is now able to fly high and no longer remain under others' influence. How can we stop Fa Zheng from behaving as he wishes?" Zhuge Liang was aware that Liu Bei greatly favoured and trusted Fa Zheng, which was why he refused to intervene in this matter.^{[Sanguozhi 16]}

The historian Sun Sheng criticised Zhuge Liang's attitude towards Fa Zheng's abuse of power and called it a "lapse in justice". He felt that no subject should be above the law, regardless of how great his past contributions were.^{[Sanguozhi zhu 5]} While Tang Geng (唐庚), a scholar from the Song dynasty, in his work called the Three Kingdoms Miscellaneous Cases (三國雜事; Sanguo Zashi) compared Fa Zheng to Fan Ju (范雎), Li Guang and Guo Jin (郭進). The three of them were allowed to settle their personal grudges and rendered great achievements for their States. Tang Geng commented that this is how rulers of the past made use of their outstanding and heroic individuals. That they had their own conceptions of righteousness. Tang Geng called Sun Sheng shortsighted for not seeing this.^[7]

In 217, Fa Zheng urged Liu Bei to attack Hanzhong Commandery, which was originally under Zhang Lu's control but was conquered by Cao Cao in 215. He pointed out Hanzhong's strategic importance and said that it was an opportune moment for Liu Bei to seize Hanzhong from Cao Cao's generals Xiahou Yuan and Zhang He. He told Liu Bei: "Cao Cao with a single strike was able to submit Zhang Lu into surrender and acquire Hanzhong, however he did not press his advantage to conquer Ba and Shu. Instead he returned North and left Xiahou Yuan and Zhang He. This cannot be an error of his part or because of a lack of strength, but rather because he met some internal problems and must solve them. Now Xiahou Yuan and Zhang He can't compare against our army. If we advance, we will surely capture them. Then we can collect grains, fill our storehouse readying ourselves for any opportunities. If we are successful we can vanquish the enemy and restore the ruling House, otherwise we can expand our borders into the Liang province and in any case we would have gain a most important position to defend and prepare ourselves. Heaven is on our side, you must not lose this chance." Liu Bei accepted his plan and started the Hanzhong Campaign with Fa Zheng following him.^{[Sanguozhi 17]}

In 219, during the Battle of Mount Dingjun, when Xiahou Yuan led troops to attack Liu Bei's camps at Dingjun and Xingshi mountains, Fa Zheng suggested Liu Bei to strike the enemy. Liu Bei ordered his general Huang Zhong to lead his men on a charge down the mountain towards Xiahou Yuan's forces, with war drums beating in the background. Huang Zhong defeated and killed Xiahou Yuan in the midst of battle.^{[Sanguozhi 18]}

Later, when Cao Cao was leading his forces from Chang'an to reinforce Hanzhong, he received news about the strategy proposed by Fa Zheng to Liu Bei to attack Hanzhong. He remarked, "I know Xuande (Liu Bei) is not capable of doing this. He must be following somebody's advice."^{[Sanguozhi 19][8]} According to the Chronicles of Huayang, Cao Cao also said: "How could it be that among my army of bold heroes, none could find a strategy that would overcome this Fa Zheng?"^[9] The historian Pei Songzhi commented that Cao Cao made that former remark – which suggests that Liu Bei was not wise enough to notice Hanzhong's strategic importance – because of his personal disdain for Liu, and that it should not be taken seriously. He felt that a lord acting on his adviser's suggestion should not be interpreted as a sign that the lord was not wise enough to make his own judgment. He pointed out that Cao Cao himself also followed the advice of his adviser Guo Jia.^{[Sanguozhi zhu 6]}

In 219, after Liu Bei emerged victorious in the Hanzhong Campaign, he declared himself "King of Hanzhong" (漢中王) and appointed Fa Zheng as the Prefect of the Masters of Writing (尚書令) and General Who Protects the Army (護軍將軍). Fa Zheng died in the following year at the age of 45 (by East Asian age reckoning). Liu Bei cried for days when Fa Zheng died and awarded Fa the posthumous title "Marquis Yi" (翼侯), which literally means "marquis of the flank". Alone, the Yi (翼) word/title is more commonly translated as "wing". Therefore, Fa's posthumous title can also be translated as "marquis of the wing".^{[Sanguozhi 20]}

During Liu Bei's short reign, many of his long term companions and famous generals had died. Among them were Guan Yu, Zhang Fei, Ma Chao, Pang Tong and Huang Zhong; yet Fa Zheng was the only one to receive a posthumous title,^[h] such was the extent to which Liu Bei valued Fa Zheng. Fa Zheng's son, Fa Miao (法邈), received the title of a Secondary Marquis (關內侯) and served as a Commandant of Equipage (奉車都尉) and the Administrator of Hanyang Commandery (漢陽郡) in the state of Shu Han, which Liu Bei established in 221.^{[Sanguozhi 21]}

Fa Zheng and Zhuge Liang did not share the same moral beliefs but they had a good working relationship because of their common goal, which was to serve Liu Bei well. Zhuge Liang was very impressed with Fa Zheng's brilliance. In 221, before the Battle of Xiaoting, many of Liu Bei's subjects advised their lord against going to war with his former ally, Sun Quan, who seized Jing Province from Liu in 219 and executed Liu's general Guan Yu. Liu Bei ignored them and proceeded with his campaign against Sun Quan. In the following year, he lost to Sun Quan's forces at the Battle of Xiaoting and had to retreat to Baidicheng, where he died in 223. Zhuge Liang sighed, "If Fa Xiaozhi was still alive, he could have prevented our lord from going on this eastern campaign; even if our lord did go on this campaign, he wouldn't have ended up in this disastrous situation (if Fa Xiaozhi was with him)."^{[Sanguozhi 22]}

Zhuge Liang might be right about Fa Zheng, as inferred from an incident during the Hanzhong Campaign. During one battle, when the odds turned against Liu Bei, Liu's subjects urged their lord to retreat but he stubbornly refused. They did not dare to advise him again for fear of incurring his wrath. Fa Zheng rushed forth and stood in front of Liu Bei when Cao Cao's forces rained arrows on their camp. Liu Bei told Fa Zheng to stay under cover to avoid the arrows, but Fa insisted on braving the arrows with his lord. Liu Bei then decided to retreat together with Fa Zheng.^{[Sanguozhi zhu 7]}

Chen Shou, who wrote Fa Zheng's biography in the Sanguozhi, appraised Fa as follows: "Fa Zheng clearly foresaw success and failure. Therefore, he had talent for all sort of unusual tactics and strategies. However, he was not known to be of good moral character. In comparison with officials from (Cao) Wei, Pang Tong would be similar to Xun Yu like a brother while Fa Zheng would be of the same nefarious kind as Cheng and Guo."^{[Sanguozhi 23]}

Yang Xi, who wrote the Ji Han Fuchen Zan (季漢輔臣贊; pub. 241), a collection of praises of notable persons who served in the Shu Han state, appraised him as follows: "Marquis Yi (翼侯; Fa Zheng) was talented for stratagem, could anticipate both rise and decline of the world. Entrusted with the foundation by his Lord, he answered with correct instruction and counsel. With a swift thought he managed his calculation, would observe the situation and perceive the opportunity."^{[Sanguozhi 24]}

Fa Zheng became a playable character in Koei's Dynasty Warriors 8: Xtreme Legends.
