After the Cultural Revolution ended in 1976, Wang was determined to work harder to compensate for the six years he had lost due to the political upheaval. He was invited to give lectures at different universities and conferences, and responded to letters of inquiry of different areas including writing, Pinyin learning and foreign language acquisition. Wang put together a large amount of his works into books, including "The General Principles of Ancient Chinese", "The History of Chinese Phonology", and "The Dictionary of Paronyms". He also started to revise the "A Draft History of the Chinese Language" at the age of 80, and expanded his original work "A Draft History of the Chinese Language" into "History of Chinese Phonology, History of Chinese Syntax" and "History of Chinese Lexicography".
