One is Hershey's ancestral home in Sandaogou, Changbai Mountain. The family is divided into three China surnames: Kang, He, Zhang and Zhang. Kang Qi, he and Zhang Zheng Bai Qi and Huang Bian Qi.
The other is Erdaogou, the ancestral home of Bakarqia family in Changbai Mountain, with white and yellow flags. Because the sixth ancestor's name was "Zhang Wutai" and he was a high official, later generations took "Zhang" as their surname. After 1966, some descendants of Zhang changed the word' Zhang' to' Zhang'.
In addition, there is Zhangjiajia in Chejiagou, Fengcheng County, which belongs to the red flag and yellow flag. Later generations were surnamed Che, Zhang and Liang respectively. Do not rule out following Zhang's surname.
It's hard to say which family your family belongs to now. You'd better go back to your hometown and ask the older generation.
