There wasn't a clear standard for the number of questions written by the books for the Chinese and Western medicine assistant physician examination. This was because the content of the examination was written by the National Unified Examination Center, while the books were written by various publishing houses. However, generally speaking, books from authoritative medical or traditional Chinese medicine publishing houses would have a higher rate of questions in the examination for assistant doctors of traditional Chinese and western medicine. For example, the People's Medical Press, China Traditional Chinese Medicine Press, Science Press, and other publishing houses had a certain degree of authority and practicality. It is recommended that candidates can choose a suitable book for the exam according to their actual situation and needs.
