On 21 January 2011, Leung Kwok-hung led a group of protesters to a public forum with a toy model car. He then smashed the car in front of Henry Tang to represent a fatal car crash. On 30 January 2011 eight youth groups including Hong Kong Federation of Students marched to New World Development, Li Ka Shing's Cheung Kong Holdings in Central and accused the government of colluding with businesses in maximising profits while squeezing the poor. The students criticised Tang and the government for policies that benefit the upper class only like no real estate tax duty, reduction of wine and profit tax. The students said the whole HK is at the mercy of real estate developers.
