During the Cultural Revolution, Hu was purged twice and rehabilitated twice, mirroring the political career of Hu's mentor, Deng Xiaoping. In 1969, Hu was recalled to Beijing to be persecuted. Hu became "number one" among the "Three Hus", whose names were vilified and who were paraded through Beijing wearing heavy wooden collars around their necks. The other two "Hus" were Hu Keshi, who was the second most senior member of the Communist Youth League, and Hu Qili, who was third most senior in the Communist Youth League and who had also become a close associate of Deng Xiaoping. After being publicly humiliated, Hu was sent to an isolated work camp to participate in "reformation through labour" under strict security. While in political exile Hu was forced to work hauling large boulders by hand.
