Lai Min, courtesy name Jingda, was a man of Xinye County in Yiyang Commandery and a descendant of Lai Xi. His father Lai Yan was Minister of Works of the Han. When great turmoil broke out at the end of the Han, Lai Min fled to Jing Province with his elder sister's husband. Because his brother-in-law Huang Wan was a nephew of Liu Zhang's grandmother, Liu Zhang sent men to bring Huang Wan's wife to him, and Lai Min too entered Shu with his sister and was always a guest of Liu Zhang. Records, Shu 12 §39
Lai Min read widely in many books, excelled in Zuo's Spring and Autumn Annals, and was especially precise in the glosses of the Cangjie Chapters and the Erya, and he liked to correct the written characters. Meng Guang, who favored the Gongyang Spring and Autumn Annals and disparaged the Zuo Commentary, constantly argued with Lai Min over these two interpretations, and Meng Guang was always loud and clamorous. Records, Shu 12 §39 · 30
When the First Sovereign, Liu Bei, pacified Shu, learning had declined after long years of turmoil, so he gathered the classical texts and sifted through the various schools of learning. Xu Ci and Hu Qian became Academicians and, together with Meng Guang, Lai Min and others, took charge of the old texts. The First Sovereign appointed Lai Min Colonel in Charge of Learning, and when he established the crown prince, made him Steward of the Crown Prince's Household. Records, Shu 12 §27 · 40
When the Later Sovereign, Liu Shan, ascended the throne, Lai Min became General of the Household Rapid as Tigers. When the Chancellor Zhuge Liang was staying in Hanzhong, he requested Lai Min and made him Army Libationer and General Who Supports the Army, but Lai Min lost the post after being implicated in an affair. After Zhuge Liang's death he returned to Chengdu and became Grand Prolonger but was dismissed again; later, after several transfers, he became Grandee of Splendid Happiness but was again implicated in a fault and dismissed. Chen Shou wrote that the repeated demotions and reductions he suffered were all because he did not restrain his words and his conduct departed from the norm. Records, Shu 12 §40
In the 7th year of Yanxi (244), when the Wei army reached Xingshi, Fei Yi was given the tally of authority and led the troops out to resist it. The Grandee of Splendid Happiness Lai Min came to take leave of Fei Yi and asked him to play a game of weiqi. Urgent dispatches were flying back and forth, and the men and horses were armored and ready to set out, yet Fei Yi gave his mind to the game without showing any sign of impatience. Lai Min said, 'Just now I was merely testing you. You are truly a reliable man and will surely deal with the enemy', and when Fei Yi arrived the enemy withdrew. Records, Shu 14 §25
At the time Meng Guang too did not guard his tongue and his opinions went against the times, but he was still better than Lai Min; both were treated with courtesy by the world as aged and esteemed scholars. Because Lai Min came from a renowned family of Jing and Chu and was a former official of the crown prince's household, he received special favor, and even after being dismissed he was employed again. Later he was made General Who Upholds Caution, with the intention that the weight of the office would make him caution himself. Lai Min died in the Jingyao era at the age of ninety-seven. Records, Shu 12 §41
His son Lai Zhong was also widely read in the classics and had something of Lai Min's manner, and together with the Master of Writing Xiang Chong and others he ably assisted the General-in-Chief Jiang Wei. Jiang Wei thought well of him and made him an Army Adviser. Records, Shu 12 §41
In his assessment Chen Shou said that Xu Ci, Meng Guang, Lai Min and Li Zhuan were widely read and had heard much, and that Yin Mo was versed in the Zuo Commentary; although they were not praised for virtuous conduct or achievement, they were truly all scholars of their age. Records, Shu 12 §102
