There are so many criminal lawyers. Will these lawyers stop taking other cases?

Lawyers should also pay attention to professionalism after practicing, and focus on a certain field to stay ahead of others. If they take everything and learn everything, they may be scattered but not refined, which will eventually affect the efficiency of enterprises. So many lawyers focus on one field and give up cases in other fields. Of course, this is not absolute. For example, if a criminal lawyer can take simple civil cases, he will take them, but only in simple cases. If it is too complicated, he will also refuse. After all, this is not his own professional field, and he can't compete with lawyers who have studied this field for a long time.
