Prince Gong Yixin is the son of Emperor Xianfeng's sixth brother Daoguang and his biological mother Empress Xiaojing. During the reign of Tongzhi and Guangxu, he was an important historical figure in the late Qing Dynasty, in charge of state affairs and foreign affairs.

Prince Gong was clever and proficient in civil and military affairs since he was a child, and won the appreciation of Daoguang.
