Is there only one gate in Litang Prison in Guangxi?

Guangxi Litang Prison has only one gate. At present, Litang Prison is separated from enterprises, most brick factories, cement factories and starch factories have gone bankrupt, and only sugar factories, water plants and pig farms are still operating normally. The pig farm is very big, with tens of thousands of pigs. A few years ago, the retail price of pork was nearly one catty in 30 yuan. At that time, there would be money without African pigs. There used to be several big characters of Litang Prison at the gate, but I don't know why. The prison is located at the junction of Yangqiao Town and Xingbin District in Laibin City, nearly 30 kilometers away from Litang.
