"I think it's a slap in the face of the Hong Kong people. We don't like the Beijing government hand pick our leaders."
Meanwhile, members of the Falun Gong spiritual movement, driven underground in China after being declared a cult in 1999, also staged a silent protest against Hu's visit.
The man himself did not seem too concerned - later signing a guest book at Government House and posing with the outgoing and incoming Hong Kong leaders and their spouses before an official dinner banquet.
Hu is also scheduled to lead Leung Chun-ying's inaugural ceremony on Sunday.
