The red tourism in the Guangdong-Hong Kong-Macao Greater Bay Area has unique characteristics in the country. Among them，the cultural resources of the Chinese people during the period of anti-aggression and anti-feudal revolution and the period of socialist construction and reform and opening up set up a distinctive red flag in the Greater Bay Area. There are good opportunities for the development of red tourism in the Greater Bay Area. The red tourism is in huge demand，red attractions and routes have been steadily constructed，and red cultural and artistic products promote reputation；however，there are problems such as the insufficient red tourism brands and single presentation of red tourism，and insufficient integration into the red tourism society needs to be solved urgently. Therefore，the development of red tourism in the Greater Bay Area should focus on exploring high-quality development paths for the supply of red tourism，and building a red tourism brand with advanced socialist culture of reform and opening up.
