After the Canton-Hong Kong strikes of 1925 and 1926, the government moved towards greater integration of Eastern culture, increasing the number of Chinese courses. In 1927, a degree in Chinese was created. Donations from wealthy businessmen Tang Chi Ngong and Fung Ping Shan – after whom two campus buildings are named – triggered an emphasis on Chinese cultural education. In 1937, the Queen Mary Hospital opened. It has served as the university's teaching hospital ever since. In 1941, the Japanese invasion of Hong Kong caused damage to university buildings, and the university closed until 1945, during this period, the Medical College of The University of Hong Kong moved to Chengdu to run a school.
