Chan was born in Hong Kong in 1990 and studied engineering and business administration at the Hong Kong Polytechnic University. He first participated in politics when he joined the 2014 Hong Kong protests against the Chinese government's decision to set restrictions on the nominating method of the candidates for the 2017 Hong Kong Chief Executive election. He was one of the protesters who went to the scene after the police's clearance of the "civic square" occupied by the protesters on 27 September.
Political activities
Chan was dissatisfied with the student leaders in the protests and called for more radical and militant approaches. He blamed the leaders of the Hong Kong Federation of Students for the failure of the movement, and launched the disaffiliation campaign to separate the Hong Kong Polytechnic University Students' Union from the HKFS membership as the convenor of the HKPU Disaffiliation Concern Group. The HKPUSU eventually passed the threshold of 1,700 votes in the referendum, with approval for disaffiliation winning with 1,190 votes. After the disaffiliation campaign, Chan began to strive for Hong Kong independence. On 28 March 2016, Chan established the Hong Kong National Party. Chan's move drew attacks from the Chinese state media and Hong Kong government. An editorial piece in the Chinese government-owned Global Times slammed the Hong Kong National Party by stating that it is "impossible to achieve" independence for Hong Kong and calling it "a practical joke" and "proliferation of extremism in Hong Kong". The State Council's Hong Kong and Macau Affairs Office issued a statement through the official Xinhua News Agency on 30 March 2016, following the declaration of the formation of Hong Kong National Party, condemning the party "has harmed the country's sovereignty, security, endangered the prosperity and stability of Hong Kong, and the core interests of Hong Kong..." The Hong Kong government issued a statement after the formation of the party, stating that "any suggestion that Hong Kong should be independent or any movement to advocate such 'independence' is against the Basic Law, and will undermine the stability and prosperity of Hong Kong and impair the interest of the general public…"
In the 2016 Hong Kong Legislative Council election, Chan's candidacy in the New Territories West was questioned by the returning officer of the Electoral Affairs Commission. The EAC required Chan and all other candidates to sign an additional confirm form to declare their understanding of Hong Kong being an inalienable part of China as stipulated in the Basic Law of Hong Kong. Chan refused to sign the form and his candidacy was "invalidated" along with five other pro-independence activists after the end of the nomination period. The Hong Kong National Party launched a rally on 5 August which was dubbed the "first pro-independence rally in Hong Kong" against the EAC's disqualifications.
2019 Osaka G20 Summit and Anti-extradition bill protests
On June 27 2019, Chan arrived in Osaka, Japan to join the separatists from China for a demonstration against the CPC. Prior to his arrival in Osaka, Chan was detained by the local authorities for 3 hours.
2019 arrests
On August 2 2019, Chan, along with a group of seven others, were arrested during a police raid on a flat in an Industrial Building on Au Pui Wan Street in Sha Tin. The group were detained for offences including possession of explosives without licence, possession of offensive weapons, and selling poisons without licence. Police found two bows and six arrows inside the flat, as well as a suspected petrol bomb, materials for petrol bombs and oils containing cannabis-derived substances. Chan was arrested again on 30 August for rioting and assaulting a police officer at the 2019 Sheung Shui protest as he tried to make his way to Japan.
