The Hong Kong Garrison of the Chinese People's Liberation Army (PLA) conducted the 22nd rotation of its members in the early hours of Thursday morning. The garrison rotation has taken place in Hong Kong since 1997. Approved by China's Central Military Commission, the rotation is an annual routine in line with the Law of the People's Republic of China on Garrisoning the Hong Kong Special Administrative Region, which stipulates that "the Hong Kong Garrison shall practice a system of rotation of its members."
