How about Shanghai Taisheng Pulp (Group) Co., Ltd.
Taisheng trading co., ltd. is a pit. It goes in and comes out. The company has no humanity, working overtime for many years, only social security, and nothing else. There are many connections and nepotism. It's a paradise for bad guys. As long as you can curry favor with the leaders, you will flatter them and earn more than anyone else. In a word, it's too dark to your imagination.
