Sūn Huán appellation Shūwǔ was [Sūn] Hé’s son. (1)
- (1) Wúshū states: Hé had four sons. The eldest Zhù was Chief of Qū’ē. The next Yì was Chief of Hǎiyán. Both died young. The next was Huán. In appearance he was upright, he was uniquely intelligent and bright, extensively learned with good memory, and able to answer in any discussion. [Sūn] Quán once praised him as their clan’s Yán Yuān, and promoted him to Commandant of the Martial Guard. He followed in attacking Guān Yǔ at Huáróng, enticed Yǔ’s remnants [to surrender], gained five thousand men, along with a great number of oxen and horses and military equipment.
Aged twenty five years, he was appointed Gentleman-General Calming the East, and with Lù Xùn together resisted Liú Bèi. Bèi’s army was many and flourishing, covering mountains and filling valleys. Huán grasped his blade and exerted himself, joining all his strength together with Xùn, and Bèi was thus defeated and fled. Huán cut off the Kuí road and intercepted all the strategic paths. Bèi climbed over the mountains and crossed difficult terrain and so only barely escaped, and angrily he sighed and said: “When I previously first visited the capital, Huán was merely a small child, but now he has oppressed me to this!”
Huán for his achievement was appointed General Establishing Martiality and given fief as Marquis of Dāntú. He went downstream to Niúzhǔ, repaired the fortifications and docks along the Jiāng, and there died. (2)
- (2) Wúshū states: Huán’s younger brother Jùn appellation Shūyīng. By nature he was tolerant and generous, talented in both civil and military affairs, and was appointed Internal Gentleman-General Settling Martiality, with a garrison at Bóluò. Chìwū thirteenth year  he died. His eldest son Jiànxí succeeded, and was General Pacifying Caitiffs. His youngest son Shèn was General Defending the South. Shèn’s son Chéng was styled Xiǎnshì.
- Wénshìzhuàn states: Chéng was good at his studies, had literary works, composed illustrious rhapsodies in his time. He was appointed Yellow Gate Attendant-Gentleman, and with Gù Róng both became Attendant Ministers. In the time of Guīmìng [Sūn Hào] the internal Attendants frequently had offenses, and only Róng and Chéng alone remained intact, and so these two were employed to record events, Chéng answering and Gù asking, and so an Imperial Order was sent down that said: “From now onward, those employed as Attendant-Gentlemen are to be of the same sort as Chéng of the Imperial Clan and Gù Róng.” After Wú was pacified he went to Luò[yáng], was appointed Magistrate of Zhuō in Fànyáng, and had many praised accomplishments. During Yǒng’ān [304-305], Lù Jī was the King of Chéngdū’s [Sīmǎ Yǐng] Chief Commander, and he invited Chéng to be his Staff Major, and as a result both came to harm.
