Can a trainee lawyer only work with a guidance lawyer?

Someone once asked a trainee lawyer to represent the case, and the trainee lawyer followed up the case in the name of legal aid. Later, the client blamed the legal assistant for not doing a good job, but did not know that the legal assistant could not represent the case. In fact, other lawyers represent the case in court, and then the client contacts the lawyer who appears in court. The lawyer shirked that he was only nominally representing the case, but in fact it was the legal assistant who followed up the case and the parties went to the legal assistant. The legal assistant said that the lawyer written in the document would find a lawyer, the client would collapse and the story would be over. If everyone understands the difference between a trainee lawyer and a licensed lawyer, this misunderstanding may be reduced. Only those who have passed the national judicial examination can apply to the local bar association for an internship certificate. As for what information the local lawyers association requires the applicant to provide, it can be adapted to local conditions and should not be put on the job when applying for the internship certificate. Weibo asked for teaching, honestly asked the local lawyers association, and made more phone calls to ask the office administrator. Don't spend too much time on this link.
