Personally, I prefer diligent teachers, such as professors from Northeast Normal University and those from Beijing. I feel more organized, more organized.

Online classroom is a new way of learning, which is a series of learning tutorials provided for learners based on the Internet, including video, pictures, text interaction and other forms. Online courses are online learning courses provided by service organizations. Different from offline classroom teaching, online classroom has the advantages of various ways, flexibility and convenience, and more and more students and parents are beginning to use it.
