The Guangdong-Hong Kong-Macao Greater Bay Area Culture: Three Treasures of Lingnan Series is a set of brief and illustrated introductions to three traditional art forms -- Guangdong opera, Lingnan school of painting and Guangdong music -- in south China. We hope these three riveting books, including Love on the Stage, Beauty of Colors and Cadence of Strings, can attract more overseas readers who love Chinese and Lingnan culture to explore further their artistic and unique charm and history. Beauty of Colors: A Little History of Lingnan School of Painting tells the history, development and influence of the Lingnan School of painting. It also introduces masters of the school including Gao Jianfu, Gao Qifeng, Chen Shuren and so on. The status of Lingnan Painting in China can also be found in this book. Since the beginning of reform and opening up in 1978 and with the rise of China's economy, Chinese culture has become more and more influential in the world. As an important part of Chinese culture, Lingnan culture plays a key role and it manifests itself most notably in art, Cantonese opera, architecture and food. More and more young people of the overseas Chinese need to know the root and development of culture of their parents and ancestors. Moreover, foreigners who are interested in Chinese culture and history also want to learn this remarkable and robust culture.
