Let's be realistic. This institution is not bad in Changsha. I passed the intermediate exam of 14 and the advanced exam of 18 at one time. Learning is always my own business, so I am a teacher. . There are so many teachers in Changsha that several institutions have similar classes back and forth. They don't study hard and complain about this and that every day. Why not buy this qualification certificate yourself? Learning mainly depends on oneself, and training institutions only provide a learning platform.
