Zhao Ziyang
Despite his suffering during the Cultural Revolution, Yang worked hard and took a leadership role in the building of a major reservoir which solved a key irrigation problem. Zhao Ziyang, the new reformist Party Chief of Sichuan, was impressed by his performance and promoted him first to Party Chief of Leshan prefecture in 1977, and only a year later, to Vice Governor of Sichuan province. Yang became a close assistant of Zhao Ziyang.
