This piece of jade belongs to Beijing Jade Group Shanghai Branch. They have their own branches in first-tier cities all over the country. Although not as big as Dana, they are very meticulous in class and employment arrangements. Every link has a special teacher in charge, and the lectures are also very detailed. If you don't understand, you can communicate with the teacher easily. There are also special teachers to take care of your life. Last time one of my classmates was ill, the class teacher gave soup every day. The whole four-month learning process is humanized, less noisy and tasteless, and what I have learned is also very practical after work.
