Is the so-called Qingbei net laugh reliable?
Great in teaching. His math, Chinese and English tutors are all good. My child signed up for math and his classmates signed up for English. They all gave a good evaluation of this family. It's really taught by 100% Tsinghua Peking University teachers, and there are usually one-on-one tutoring assignments by the head teacher, which is very serious. If children want to teach themselves and are conscious enough, they can try, but personally, online schools lack interaction, and the effect is definitely much worse than that in the classroom.
