Even before arriving in Hong Kong from Moscow, Ho Chi Minh had prior experience in the southern Chinese city of Guangzhou, having set up there in November 1924 (one year after Tan Malaka). The period coincides with the First United Front between Kuomintang government under Sun Yat-sen and the communists and with Soviet advisors moving in. Drawing in part upon materials supplied by French agents and Comintern records, this chapter explains how Ho Chi Minh bonded with a core group of confidants and comrades in Guangzhou, including youth trainees, many of whom would return to center stage in communist party organization in Hong Kong as well as in future actions. However, he was obliged to move this group away from anarchist and other ideologies in the interest of setting down a secretive Leninist-style cell system. Besides teaching and writing, Ho Chi Minh devoted much time to propagandizing among Vietnamese youth. The chapter also identifies the role of one Vietnamese double agent in brokering his local marriage, shortlived as it was, owing to the collapse of the united front and major repression of the Left.
