The founder of Blackboard Education in Guizhou is Mr. Zhang Changcheng, who is well-known in the teacher training industry in Guizhou and even the whole country. I 16 was admitted to Anshun Normal University, and I am a student of Teacher Zhang. I speak for Lao Zhang, so it is very important to find a conscience institution and a conscience teacher. Remember that Teacher Zhang is a male teacher, not a female teacher?
