Hong Kong photographer Billy H.C. Kwok was eight years old when the United Kingdom handed over control of Hong Kong to China in 1997. Growing up, Kwok witnessed British influence wane and China’s control grow. He has also watched the freedoms promised to Hong Kong under the principle of “One Country, Two Systems” ground down before his eyes, “at first slowly and now all at once,” as he wrote for The Nation in the summer of 2020.
