Erzhu Shilong
Late in 530, Emperor Xiaozhuang, apprehensive that Erzhu Rong would eventually seized the throne, ambushed him in the palace and killed him. Erzhu Rong's cousin Erzhu Shilong and nephew Erzhu Zhao rebelled, declaring Erzhu Rong's wife Princess Beixiang's nephew Yuan Ye the Prince of Changguang emperor. However, Erzhu Tianguang initially took no corresponding action; rather, when Emperor Xiaozhuang sent his official Zhu Rui (朱瑞) to try to persuade Erzhu Tianguang to join his side, Erzhu Tianguang deliberately made ambiguous gestures, trying to instead encourage Emperor Xiaozhuang to abandon Luoyang and flee, rather than to directly confront the emperor. Both Emperor Xiaozhuang and Yuan Ye conferred princely titles on Erzhu Tianguang, and Erzhu Tianguang eventually accepted Yuan Ye's bestowment of the Prince of Longxi title, but did not make further threatening gestures against Emperor Xiaozhuang. Around the new year 531, Erzhu Zhao made a surprise attack on Luoyang and captured it and Emperor Xiaozhuang, and only then did Erzhu Tianguang go to Luoyang to meet with Erzhu Zhao and Erzhu Shilong, but soon returned to his post at Chang'an.
