Huaiqing House has belonged to Henan since ancient times!
The ancient river refers to the Yellow River, Henan refers to the south of the Yellow River, and Hebei refers to the north of the Yellow River.
Now Henan does not refer to the south of the Yellow River, but also Anyang, Hebi, Xinxiang, Puyang, Jiaozuo, Jiyuan, Sanmenxia and Luoyang.
