I don't comment on the red sun tutor! But there are good counseling centers recommended to you, Huanhuan counseling website, search Huanhuan in Xinjiang on Baidu, or Huanhuan in Urumqi. They have many teachers and students, but most of them are one to one. If you want to follow the class, there are also cooperative classes. Want to find an undergraduate tutor, no charge. Their telephone number is 099 1-78234 14. 099 1-3664289。 By the way, I'm not a trustee. I just found a tutor there. I feel very formal and comfortable. Let me give you a reference.
