According to Zhihu, there are more topics with higher quality. There are relatively few topics in Wan Wei, but one book has more topics and higher quality, which can better meet students' learning needs, help students better master knowledge and improve their academic performance.

Knowledge point coverage is more comprehensive. A teaching assistant covers mathematics, physics, chemistry, geography, biology, politics and other subjects, and the content is relatively comprehensive. Wan Wei's teaching assistants mainly explain one or several subjects in depth, and the coverage of knowledge points is relatively small.

Pay more attention to the cultivation of students' thinking ability. Each chapter in the teaching aid has a link of "scientific inquiry" and "thinking extension", which can guide students to improve their critical thinking ability and creative ability by solving problems. The teaching assistants in Wan Wei pay more attention to problem solving and skill teaching.

The price is closer to the people. The price of a teaching assistant is cheaper than that of Wan Wei, which is a better choice for some students who are not particularly well-off in economic conditions.
