The online tutors of OxSC Niu Jian Academic Summer School 1 to 1 are all teachers who graduated from Oxford and Cambridge University. Don't worry about their conduct at all, because my children have accompanied me to class. After all, they all graduated from prestigious schools. The purpose of online teaching is to make students have better academic performance and a perfect future, which coincides with the original intention of all our parents. These teachers are excellent teachers who have been screened out through multiple tests such as teaching and conduct. On the other hand, I think that as our parents, we should also give more trust to Niu Jian's tutor, so that parents, teachers and students can cooperate reasonably and complete the initial learning concept. I would appreciate it if you could take my answer. If you need anything else, you can ask, thank you!
