From the car depot to Pengshui, a large billboard attracted my attention. The slogan was very interesting - "Gongtan Ancient Town, Grandpa's and Grandma's Home. At that time, I thought it was very interesting. I drew a picture of my grandparents'house in my mind. Later, I learned that this is the evaluation of Gong Tan by Mr. Wu Guanzhong, a master of Chinese painting. The original words are : Tang Street, Songcheng, Grandpa's and Grandma's home.
