When Leung was young, he asked the reasons for political events in Hong Kong, such as Handover of Hong Kong in 1997 and 1st July marches in 2003. He then started joining some political events in 2008, when he was 17. The first two being the memorials for the 1989 Tiananmen Square protests and the 1st July marches. He was touched by people fighting for democracy. In Summer 2014, the government of People's Republic of China passed "831 decision" and White paper, making Leung not believe that the HKSAR government will follow Sino-British Joint Declaration.
