I have just changed from an intern lawyer to a full-time lawyer, and I can answer this question responsibly. Intern lawyers can't handle cases independently. In Shanghai, even a trainee lawyer can't enter the detention center, even if he follows the lawyer in charge. If there is a source of the case, you must share it with other lawyers. How to divide it depends on how deeply you are involved in this case.
If you only introduce cases, it is generally around 20% to 30%. If you are involved in this case, you can get more points. As a trainee lawyer, I suggest that you don't have to think too much about sharing. Learning from senior lawyers is the most important thing.
