According to different research topics, the proportion is not fixed, and there is no formula for the number of Chinese and English articles. The cited Chinese documents are divided into two categories: those who demonstrate the general situation comprehensively must be celebrities, and those related to the research content of this book can be quoted at will. It should be noted that domestic colleagues can quote in both Chinese and English, but they must quote positively.

10-20 articles should be appropriate. After all, there are not many first films. Information should be cutting-edge and up-to-date, or influential in related disciplines. English accounts for more than half, but well-known domestic colleagues should also mention it. Otherwise, you won't be happy if others see me doing this in peer review!
