Zhu Chen Zhiyi is also called Zhu Chen Zhihao, which means that the two families are married.
Zhu Chenzhihao means that the two families are getting married. From Bai Juyi's poem "Zhu Chen Village": "In Gufeng County, Xuzhou, there is a village called Zhu Chen. There are only two surnames in one village, and they have been married for generations. The two characters Zhu and Chen have become the synonyms for the marriage of the two surnames, alongside "Qin and Jin".
