How to evaluate the significance of Li Zhuang case in the reform of criminal procedure?

In the sensational case of cracking down on criminals in Chongqing, lawyer Zhuang Li was criminally detained by Chongqing public security organs on suspicion of falsifying evidence and obstructing testimony. This case does not talk about the dispute between crime and non-crime. From the procedural point of view, there are many places worthy of scrutiny. The reason is that China's legislative provisions are not clear, and the criminal procedure is also lacking and needs to be improved.
