On 6 March 2010 Tang attended a Youth Summit in Chai Wan organised by the Home Affairs Bureau. A 31-year-old jobless man threw a shoe at Tang and it landed on the stage metres away from him. The man was dragged away by police. The man said he was unemployed after getting fired by a computer company, and the government policies were not helping him. He said he was not a "post-80s" teen, but supported the highspeed rail protest connecting HK to Guangdong. A protester said that the topics discussed in the summit are not those that any young person would be interested in.
