The reason why Luo Xiang can't be a lawyer is that he is a law professor, not a lawyer. Although Luo Xiang has profound legal literacy and broad worldly wisdom, and his lectures are true, personalized, humorous and vivid, and he can treat the law as a "cross talk" and a "joke", he has not received formal legal training and judicial practice. According to the Law on Lawyers, lawyers cannot accept cases that involve their own interests or may affect their own interests, and Luo Xiang participated in the revision of relevant laws and regulations, so he cannot participate in relevant cases.
