There is no fixed answer to the question of who Li Nan and He choose in the course of physical network. Because which teacher to choose depends on one's learning style and needs.

First, understand the teaching style.

First of all, we should understand Hehe's teaching style. You can watch their speech videos or listen to other students' comments to understand their performance in class. Li Nan's teaching style may pay more attention to heuristic teaching, and cultivate students' thinking ability through problem solving and practice. William He may prefer systematic teaching, focusing on clear knowledge points and examples.

Second, consider individual learning needs.

When choosing online courses, we should also consider individual learning needs. If you are weak in physics, you may need a more systematic and detailed explanation. At this time, you may prefer to choose which online class. If you have a certain physical foundation and want to improve your physical literacy and problem-solving ability through thinking and practice, you may prefer Li Nan's teaching style.

Third, evaluate the content and difficulty of the course.

In addition to the teaching style and personal needs, it is also necessary to evaluate the content and difficulty of the online class of the two teachers. You can learn about each teacher's curriculum and difficulty level by looking at the syllabus, listening to or reading other students' comments. Choosing the appropriate course content and difficulty is the key to improve the learning effect.

Fourth, refer to other people's suggestions and experiences.

Finally, you can refer to other people's suggestions and experiences. Ask your classmates or teachers around you about the evaluation and learning experience of Hehe. At the same time, you can also search related comments and discussions online to learn more about different students' views on these two teachers.

Only by comprehensively considering the teaching style, personal learning needs, course content and difficulty, as well as the suggestions and experiences of others, can we choose the physical network course that suits us more accurately. It is important to find a teacher who can stimulate learning interest and improve learning effect, so as to achieve better learning effect.
