Introduction to Suoer Cliff: Located in the Yangzigou Longtan Scenic Area, it is the place where Fan Lihua educated her son. There is a stone ridge in the stone wall, and the protruding stones form a human face shape, which resembles a child's facial makeup. It is called Suo'er Cliff, commonly known as Shiren'er. It is said that Fan Lihua's son Xue Gang was naughty when he was young, and Fan Lihua once locked him under the cliff, hence the name Suo'er Cliff.
