魯平
After the defeat of the traditional leftist candidates in the first direct election of the Legislative Council by the pro-democracy candidates of the United Democrats of Hong Kong in the wake of the pro-democracy sentiment after the Tiananmen incident in 1991, Tsang and other leftists founded the Democratic Alliance for the Betterment of Hong Kong under the call of director of the Hong Kong and Macau Affairs Office Lu Ping to gear up the "patriotic force" in the territory. Tsang became the first chairman of the party. He was subsequently appointed to the Preparatory Committee for the establishment of Hong Kong.
