Yuan Xin

Yuan Xin ( 6th century), courtesy name Qingle, was a general and official of the Northern Wei and Western Wei during the Northern and Southern dynasties period. He was the brother of Emperor Jiemin of Northern Wei and was a high-ranking official from the imperial Yuan clan. After Emperor Xiaowu's flight to Chang'an in 534, Yuan Xin surrendered to Yuwen Tai and the Western Wei, where he eventually became one of the Eight Zhuguo (八柱國). Unlike the other Zhuguo, Yuan Xin was the only member to not hold military command; his role was mostly nominal, and modern historian, states that his inclusion was only to appease the Yuan clan, who still possessed considerable influence under the Western Wei.
