Qian Xuesen
Tsang grew his patriotic sentiments and interest in Marxism by reading the leftist newspaper "Wen Wei Po" which his father brought home from work everyday and worshipped Qian Xuesen, a renowned scientist who returned to the mainland from the United States in the 1950s. In 1966, he went back to Guangzhou with his mother and was impressed by the socialist life there. He proclaimed himself a Marxist and studied works of Karl Marx and Mao Zedong with like-minded classmates at a time when the majority of the students at the University of Hong Kong supported the colonial rule and had negative views on the communist regime in China.
