There is Beijing Dacheng (Urumqi) Law Firm on the Exhibition Avenue in Shuimogou District, which is a national law firm with branches all over the country. Larger law firms gather relatively more professionals. Previously, I searched Dacheng Law Firm through Baidu and communicated with Lawyer Yuan through WeChat. He answered my question patiently. If you have any questions, you can communicate with Mr. Yuan through WeChat and telephone first, and listen to his preliminary suggestions. You can also Baidu it.
