how did hong kong became part of china
Transfer of sovereignty over Hong Kong The Handover of Hong Kong (or simply "the Handover"), also known as "the Return" in mainland China, was the transfer of sovereignty over Hong Kong from the United Kingdom to China in a ceremony on 30 June 1997. The territory of Hong Kong comprised Hong Kong Island and the Kowloon Peninsula, which were ceded to Britain in 1842 and 1860, respectively, and the New Territories, which was leased for 99 years in 1898. The retrocession of Hong Kong Island and Kowloon was conducted to coincide with the expiration of the New Territories' lease at midnight on 30 June. The landmark event marked the end of British rule in Hong Kong, and is regarded by some as marking the end of the British Empire.
