Fa Zheng
Fa Zheng, courtesy name Xiaozhi, was a key adviser to the warlord Liu Bei in the late Eastern Han dynasty. Born in a family of high social status and of noble descent, Fa Zheng travelled to Yi Province in the late 190s and became a subordinate of Liu Zhang, the provincial governor. However, his feelings of alienation and perception of Liu Zhang as an incompetent governor eventually led him to betray Liu Zhang and defect to Liu Bei in 211. Between 211 and 214, Fa Zheng assisted Liu Bei in overcoming Liu Zhang and seizing control of Yi Province, and became one of Liu Bei's most trusted advisers. In 217, he urged Liu Bei to launch the Hanzhong Campaign to capture the strategic Hanzhong Commandery from a rival warlord, Cao Cao, but died a year after Liu emerged victorious in the campaign.
Fa Zheng's keen foresight and brilliance in formulating strategies earned him praise from his contemporaries such as Zhuge Liang and Chen Shou. In less than a decade serving under Liu, Fa showed a near unmatched sense of timing where military geniuses like Cao Cao and his best advisers fell victim to his schemes. However, he was also notorious for his vindictive personality. When he held office, he abused his power by taking revenge against those who had offended him before, and by killing them without reason. Nevertheless, he was still highly regarded and trusted by Liu Bei – to the point where Zhuge Liang once said that Fa Zheng might have been the only person capable of preventing Liu Bei's defeat at the Battle of Xiaoting in 221 if he were still alive.
Family background
Fa Zheng's ancestral home was in Mei County, Youfufeng Commandery, 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.Fa Zheng's great-grandfather, Fa Xiong, served as the Administrator of Nan Commandery 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. Fa Zheng's father, Fa Yan, whose courtesy name was Jimou, also served as a government official and held the positions of an assistant to the Excellency over the Masses and the Minister of Justice.
Service under Liu Zhang
In the early Jian'an era of the reign of Emperor Xian, when famines broke out, Fa Zheng and his friend Meng Da travelled to Yi Province to join the provincial governor, Liu Zhang. Although Fa Zheng served as the Prefect of Xindu County and later as a Colonel Who Advises the Army 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.In 208, Zhang Song travelled to Jing Province 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.
Their opportunity came in 211, 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, 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." Fa Zheng also saw Liu Bei's marital problems and advised him to have Lady Sun sent back to Wu. Liu Bei accepted Fa Zheng's former advice and led his forces into Yi Province, where he met Liu Zhang at Fu County. Liu Bei then led his troops north to Jiameng before turning south to attack Liu Zhang later.
Helping Liu Bei seize Yi Province from Liu Zhang
Upon receiving news of Liu Bei's attack, Zheng Du, an assistant officer from Guanghan Commandery 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 and Zitong 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.In 214, when Liu Bei's army surrounded Luocheng, 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.
Fa Zheng's letter was written as such:
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." Liu Bei followed Fa Zheng's advice and treated Xu Jing generously.

Service under Liu Bei
Becoming Liu Bei's Chief Adviser
Liu Bei appointed Fa Zheng as the Administrator of Shu Commandery and General Who Spreads Martial Might. 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.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.
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, 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.
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. While Tang Geng, a scholar from the Song dynasty, in his work called the Three Kingdoms Miscellaneous Cases compared Fa Zheng to Fan Ju, Li Guang and Guo Jin. 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.
