Is Han Shanwei from Jiaonan Tiantai Law Firm a lawyer?
If you want him to be an agent or defender, go to the law firm to go through the formalities. If he is not a lawyer and can't take this case, you can also show him his lawyer's license. Or check the lawyers of the local judicial department for filing and announcement, or call the lawyer management section of the local judicial bureau. Asking here means answering yes or no, which is unfounded.
