Liu Xun's Chinese International Education: An Introduction to Teaching Chinese as a Foreign Language has a solid foundation and should be read well. The theoretical part of teaching Chinese as a foreign language is still very important. Cheng, a general theory of China culture, this book is very detailed and comprehensive, and you need to sort it out yourself. This is a very powerful book; Editor-in-chief of Educational Psychology by Liu, the content is boring and theoretical, and it is not difficult to master.
There are still a considerable proportion of foreign cultural topics in the test paper, which need to be collected and sorted by yourself. It is suggested that what teenagers must know 100 1 cultural knowledge (foreign volume) is still very rich in content.
Regarding the last case analysis, I personally think that under the guidance of cross-cultural communication theory, it is enough to make sense, and no established format is needed.
This is my experience. If in doubt, please continue to ask questions.
