Du Xi

Du Xi ( 190–231), courtesy name Zixu, was an adviser to the warlord Cao Cao during the late Eastern Han dynasty of China. He was a subordinate of Cao Cao's general Xiahou Yuan. Du Xi proposed to the troops that Zhang He take command after Xiahou Yuan was killed at the Battle of Mount Dingjun. He continued serving as an official in the state of Cao Wei, established by Cao Cao's successor Cao Pi, during the Three Kingdoms period.

Before joining Cao Cao In the early 190s, when Du Xi sought refuge at Jing Province, Liu Biao treated him like an honored guest; Liu Biao repeatedly praised Po Qin (繁钦), who was with Du and was also from the same commandery as Du. Unwilling to serve Liu Biao, Du Xi then moved further south to Changsha Commandery.

Anecdotes When Cao Cao was still alive, Du Xi saw that Xiahou Shang was very close to Cao Pi, who had by then been confirmed as heir over his brother Cao Zhi. He informed Cao Cao that Xiahou was a "friend who would not be beneficial (to Cao Pi)" and should not be given such preferential treatment. When Cao Pi knew about Du's comments, he was greatly displeased.

Xiahou Shang married the younger sister of Cao Zhen. In his later years, Xiahou Shang took a concubine, whom he loved dearly. A family feud broke out when Xiahou Shang's concubine started fighting with Cao Zhen's sister to become Xiahou Shang's official spouse. When Cao Pi heard about it, he decided to intervene as a show of support for his fellow members of the Cao clan, so he had Xiahou Shang's concubine executed by strangulation.

Xiahou Shang was so upset by his concubine's death that he fell sick and his health started deteriorating. After burying his concubine, he stayed indoors all the time and refused to meet anyone. When Cao Pi heard about it, he remarked, "Maybe Du Xi had good reason(s) to look down on (Xiahou) Shang." Despite this incident, Cao Pi still highly favoured Xiahou Shang because he was a close childhood friend.

Family Du Xi's grandfather was Du Gen (杜根; 100-155), son of Du An (杜安).
