What is Dongguan Niu Shan Detention Center like?

I have consulted Zhou Naiwen, a lawyer of Dongguan Niu Shan Detention Center. He said, "The prisoners' meals should be set separately from the police canteen. Efforts should be made to adjust and improve within the prescribed standards. Food should be clean and hygienic, and boiled water should be supplied in sufficient quantities. Food accounts are settled once a month. Sick criminals and criminals of foreign nationalities may raise their food standards as appropriate.

Generally, you can save money in 500 yuan for consumption in one month. "I hope I can help you.
