"Romance of the Three Kingdoms" is one of the four masterpieces of classical Chinese literature. There are many publications, whether selective, children's or adult. However, a version written entirely in the Cantonese dialect has never been seen. In Hong Kong, Macao and overseas, there are still many readers, especially young people, who are accustomed to and willing to write in Cantonese and read works written in Cantonese. Therefore, for teenagers from high school to junior high school, it has its own unique significance to reinterpret "Romance of the Three Kingdoms" in Cantonese dialect. The introduction of Cantonese colloquialisms and related historical knowledge can help young people have a deeper and comprehensive understanding of this ancient masterpiece that embodies the essence of traditional Chinese culture.
