Textbooks are different. In the future, primary school textbooks synchronized with primary seven include English and Chinese. Most other robots don't have mathematics, and their intellectual companions don't have synchronous mathematics. At the same time, in the future, in addition to synchronizing the textbooks published by People's Education, Xiaoqi has also added many local textbooks, such as Beijing Normal University Edition, Jiangsu Education Edition, Hebei Education Edition, West Normal University Edition, Shanghai Education Edition, People's Education Edition and Hunan Education Edition, which are more abundant and more selective. There are very few textbooks in Zhiban, except the People's Education Edition.
