The ancestor of Liu surname in Yiwu can be traced back to Liu Hui, the grandson of Liu Xiu, Emperor Guangwu of the Eastern Han Dynasty. Liu Hui is the son of Liu Xiu's eldest son, Liu Qiang. After his mother, Queen Guo, was abolished, Liu Qiang was also demoted as the king of the East China Sea. One year before his death, Liu Qiang took his son Liu Hui to visit him, met Liu Hui, and named him "King of Yiyang" and "King of Wu Shangjun".

Wu Shangjun Wang Liuhui is the ancestor of Liu and Jin surnames in Yiwu. His tomb is called the octagonal tomb, and the tombstone is engraved with thirteen words "The King Table of Sun Zui County in the Eastern Han Dynasty" ... The real thing is now in the Yiwu Museum. However, when the Yiwu Municipal Government built Xiuhu Square in 2000, its tomb site was razed to the ground.

Why is Liu Hui the ancestor of Jin? During the Five Dynasties and Ten Kingdoms period, the 27th grandson of the King of Wu was appointed as the secretariat of Yuezhou. Because of the taboo of King Qian Wusu, Liu's surname was removed and changed to Jin. Liu Xie's great-grandson was renamed Liu. Genealogy records that "the descendants of the army continued to be surnamed Jin, and the descendants of the people were renamed Liu".

In the past, there was a Siqing Temple in the north gate of Yiwu, namely, Su Qing, Qingyan, Qingxi and Qingcun. This green village is named Jin. These four green temples illustrate the living conditions of the Liu family.
