Speaking of this matter, it is still quite tangled. A few days ago, I went to the evening self-study class accurately and felt like a teacher. Later, Tong Jia informed me to attend the weekend class, and I was going crazy when I came out. In fact, they are a teacher, super speechless. I planned to rest and sleep in on Saturday, but I gave up the opportunity to sleep in for study. This is still the result. I thought teachers in big companies in Tong Jia should be very good, alas! I went to the day class in Jingdezhen, and the teacher was good. The admissions teacher assured me that there would be no such thing as what I experienced. Teachers have taught here, and I think such teachers are responsible enough. You can also have a look these two days.
