Look at the law firm mainly to see what suits you. Different lawyers may have different understandings of the same legal issue, and different lawyers may have different ideas and methods to deal with the same case, as well as their ability to argue in court and their comprehensive degree of legal knowledge. The personal ability of the lawyer who handles the case for you determines the service quality of your case.
If you really have legal problems, you can go to the "Oriental Legal Cloud" to consult lawyers and find law firms all over the country. It's quite convenient.
