The world's largest collection of Mao buttons is in a museum in Jinshitan that also has lots of paintings and sculptures from the Mao era, including a bust of Bethune beside a big one of Mao. It's 100 rmb to enter but you can get in for just 20 yuan on the night of the Light Festival.

Inside the Jinshitan Mao Zedong Badges Exhibition there are more Mao badges than anywhere else in the world. There's two floors of displays, including a big replica of The Forbidden City COVERED in Mao badges. There are other sculptures, paintings, and artifacts relating to Mao, as well. The Exhibition hall is right beside a beautiful building that is the home of half a dozen other attractions, including a domed theatre, restaurants, et cetera, and it's located right across the street from the Jinshitan train station at the north-east end of Dalian.
