1, don't trust online advertisements.
For a lawyer, the professional level is almost the same. The difference lies in his litigation experience and whether he can be fully responsible.
I suggest you ask your relatives and friends. If you have contacted or entrusted a lawyer, see if there is a suitable and responsible lawyer.
When communicating with him beforehand, try to examine his character and sense of responsibility, and don't sign the power of attorney easily. Because once the power of attorney is signed, the agency fee is not refundable if you want to change people.
