I always feel uneasy about finding a tutor online. My children's tutors are all found by China Normal University. They have a special tutor center, and the teachers are all students, undergraduates and graduate students of China Normal University. You can go there to find classmates who live in Shanghai or don't go home during the winter vacation. Student tutors communicate well with children and are familiar with teaching materials.

You can call or visit their website. You can ask them any questions you want. They will post your request online. Students who want to do it will register, and then the staff will find the best one for you from several registered students.

I hope I can help you. Now children's education is a big deal!
