Even during the Cultural Revolution, Mao badges were extensively collected, traded and given as gifts. However it is unlikely that anyone was able to match the collection of Mao badges that Ye Qun, wife of Lin Biao, managed to put together at the start of the Mao badge craze. She collected several thousand different types of Mao badges to give to Mao on his 73rd birthday on 26 December 1966, although she was unable to achieve the symbolic target of ten thousand badges that she was hoping for.
