I have a say in this. Objectively speaking, leadership is quite reliable. Founded eight years ago, Lingdong is an old school in the robot education industry, and their reputation in Changsha has always been very good, mainly recruiting children aged 3- 16. Our son is leading robot programming, and the teacher is very professional in class. My son is learning programming now. Show me his works before class. It's really good. . If you are satisfied, please adopt it.
