Be patient enough. Teaching children, especially primary school students, requires patience. Many questions need to be repeated many times, and you can't teach them with your existing knowledge system. He may not understand. You may have forgotten some knowledge, so you need to review patiently so that you can teach your students well. Then be careful. Your children will think differently from you. You should be able to find problems in time and solve them in a way that he can accept. Finding a job as a tutor also requires skill. Don't believe the notes posted outside the school asking for a tutor. You can go to your school and ask if there is a campus organization that introduces tutors. The tutor center of Changsha University Student Union is also good.
