How to use social identity theory to enhance the identity of compatriots from Hong Kong, Macao and Taiwan to the mainland of China?

To enhance the recognition of Chinese culture by compatriots from Hong Kong, Macao and Taiwan and overseas Chinese, we must vigorously carry out overseas Chinese education. It is necessary to gather the resources and strength of all parties, focus on the two central links of teaching materials and teachers, vigorously support overseas Chinese to carry out Chinese education, and strive to meet the needs of overseas Chinese to inherit Chinese culture. In particular, we should further improve the Chinese teaching material system, actively develop online education and develop multimedia teaching materials; It is necessary to strengthen the training and selection of teachers, and train a group of high-level teachers through training in China, roving lectures and correspondence education. Second, we should further strengthen various cultural exchanges, run various summer (winter) camp activities under the brand of "China Root-seeking Journey", actively carry out youth work in China, attract more young people from China to study in China for a short time or receive systematic academic education, and create conditions and provide help for them to understand the long history and construction achievements of the Chinese nation. Third, strengthen cross-strait exchanges and cooperation in culture, education, art, science and technology, medicine, health, sports and ethnic groups, focus on exchange activities with grassroots people, scholars, teenagers, college students and ethnic minorities in Taiwan Province Province, actively plan and organize compatriots in Taiwan Province Province (especially those who have never been to the mainland of the motherland) to participate in exchange activities, enhance their understanding of the achievements of reform, opening up and economic construction in the mainland of the motherland, and close their emotional ties. For Taiwanese businessmen who invest, trade and engage in other industrial and commercial activities in the mainland of the motherland, they should take the initiative to care, serve warmly, strengthen friendship and close feelings; It is necessary to do a good job for students from Taiwan Province Province to study in the mainland, and take effective measures to enlighten and influence students from Taiwan Province Province with Chinese culture. Fourth, give full play to the advantages of the democratic parties and relevant people's organizations, such as extensive contacts, intensive intelligence and numerous talents, and support the democratic parties and relevant people's organizations and experts and scholars to actively participate in international folk cultural exchanges, so that the spread of Chinese culture can serve the peaceful development of China and the construction of a harmonious world.
