Based on the Shantou dialect reading, the article uses the search and sorting function of Excel to arrange the pronunciation of all the words in the book in the form of homophone vocabularies, and summarizes the phonetic system of Chaozhou dialect more than one hundred years ago. A brief comparison of Chaozhou dialects reveals the phonological evolution of Chaozhou dialects over a hundred years.
