According to the information, Guo Wengui instructed Qu Long, the former executive director of Beijing Zhengquan Company, to free up the basement of Jinquan Plaza and create partitions. His explanation was that the leadership wanted to use it to control things, which was confidential. But in fact, it was Guo Wengui who installed surveillance videos in the partitions to monitor the inappropriate behavior of these leaders and recorded them as backup. No matter in all occasions such as Yuda, Zhengquan and Pangu, Guo Wengui has used these techniques to the fullest.
