What kind of lawyer is Hang Cheng Jun Zheng?

For Jun Zheng lawyers, some clients reported that their service performance in Zhejiang Kuangzhi Law Firm was not good. The client pointed out that Jun Zheng's lawyer didn't respond positively after charging, and he didn't abide by the law firm's regulations when charging privately, which may cause clients' concerns about service quality and integrity. I hope lawyer Jun Zheng can pay attention to these feedbacks and improve the service quality.
