Michael Tien Puk-sun (born 25 August 1950) is a Hong Kong politician, businessman and member of the Legislative Council for New Territories North West. He is the founder and chairman of the G2000 clothing retail chain and former chairman of the Kowloon-Canton Railway Corporation (KCRC). He was formerly a member of the Liberal Party, which was led by his elder brother, James Tien, and a member of the New People's Party. History Tien was appointed as the chairman of the Kowloon-Canton Railway Corporation (KCRC) in December 2001 amid public criticism on his predecessor, K. Y. Yeung. He proposed and implemented administrative reforms that enhanced KCRC's transparency and accountability; he regularly attended Legco meeting and explained the company's policies and decisions. In 2006, Tien resigned as chairman of the KCRC due to disputes with other directors over his management style. Tien joined the Liberal Party in 2008 and became District Officer for Kowloon West. He quit the party in 2010 and started the New People's Party with Regina Ip, of which he became the deputy chairman. In the 2017 Chief Executive election, Tien supported his party chairwoman Regina Ip. He complained the election had "lost its shape" due to the increasing interference of "an invisible hand", referring to the Liaison Office. Tien inclined his support for John Tsang after Ip dropped out, although Ip endorsed Carrie Lam on the last day before the election. Tien eventually quit the party on 10 April with six District Councillors. In the 2019 District Council elections, Tien lost his Tsuen Wan District Council seat following a rout of pro-Beijing candidates amidst the 2019–20 Hong Kong protests. In December 2021, it was reported that Tien had a "privileged" vote in the 2021 Hong Kong legislative election, where the vote would count approximately 7,215 times more than an ordinary citizen.
