Zhang, from Wendeng County, dengzhou city, Shandong Province, wants to find his roots.

Hello, I'm from Wendeng, Shandong. There is a village in my home called Zhangjiabu. The whole village is basically surnamed Zhang, and the "Ji" generation you mentioned is the older generation here. They are all over 80 years old. I guess there will be relatives or something. You'd better ask your old man if he lives by the sea.
