There is a detention center in Poyang, which is said to be for prisoners. If you go north along Yingbin Avenue from the county town intersection, less than 10 kilometers, there is a villa area of Jiuding Villa, and at the intersection opposite to it (on the right hand side of Yingbin Avenue), you will see an uneven road with a signboard saying "Poyang Prison", which extends all the way to a forest, and then you can enter into the forest for about one kilometer.
There is another prison, Raozhou Prison, also known as Zhuhu Farm, near Yugan County. Take the Poyang Bridge and go in the direction of Sanmiaoqian - Lefeng, a distance not too well remembered.
Looking for the adoption, thank you
