The "Harmony and Progress - Celebrating the 25th Anniversary of Macau's Return and the 9th National Security Education Day - Exhibition of Famous Calligraphers and Painters from Guangdong, Hong Kong, and Macau" was held from April 7th to April 15th at the Macau Municipal Council Gallery. This exhibition is guided by the Guangdong Federation of Literary and Artistic Circles, organized by the Guangdong National Security Foundation, and co organized by the Guangdong Calligraphers Association, Guangdong Artists Association, Appreciation Hall (Macau) Calligraphy and Painting Association, and Hong Kong Yunfeng Painting Garden. A total of 64 calligraphy and painting masters from Guangdong, Hong Kong, and Macao were invited to create and exhibit 69 exquisite works by these masters. This year marks the 10th anniversary of the overall national security concept and the 25th anniversary of the return of the Macao Special Administrative Region to the motherland. Artists from Guangdong, Hong Kong, and Macao work hand in hand, using calligraphy and Chinese painting as art forms to jointly support national security education for the whole nation. They use vivid strokes to depict the colorful sublimation of the overall national security concept in the practice of "One Country, Two Systems", highlighting the patriotism and national spirit of calligraphy and painting masters from Guangdong, Hong Kong, and Macao, and reflecting the responsibility and responsibility of creators to maintain national security. Representatives of participating artists stated that the Guangdong Hong Kong Macao Greater Bay Area has rich cultural resources and rich cultural traditions, making it a place of cultural integration and gathering. I hope to have more opportunities for cultural and artistic exchanges between Guangdong, Hong Kong, and Macao in the future, to gather cultural consensus, enhance cultural confidence, and jointly draw a vivid picture of the people of the Guangdong Hong Kong Macao Greater Bay Area working together to safeguard national security, promote the stable and far-reaching implementation of the "One Country, Two Systems" policy, and promote the high-quality development of the Greater Bay Area.
