The real place where Zhao's orphan happened? Isn't it Xiangfen, Shanxi?
It happened in Fen Town, Xiangfen County, Linfen City, Shanxi Province. Now there is a tomb of Cheng Ying in Chenggong Village, and Fenyang is the birthplace of Zhao Dun. It is often called "no baby ditch" because Tu'an Gu killed all the babies in that place to mow the grass, so it became a no baby ditch. There are various indications that Zhao's orphan happened in Fen Town.
