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. When Zhao Ziyang left Sichuan to become the
Premier of China in 1980, Yang was favoured to succeed him as the provincial chief. However,
Tan Qilong, a senior revolutionary leader, was chosen instead to replace Zhao as a transitional leader to "assist" the relatively young Yang Rudai. Yang became one of the several party secretaries of Sichuan under Tan, but he took charge of the daily operation of the province. Two years later, Tan Qilong retired from politics along with most senior leaders of the revolutionary generation, and Yang Rudai succeeded him to become the first Sichuan native to serve as its top provincial leader. He was also elected to the
12th Central Committee of the Chinese Communist Party in 1982. In 1987 he rose further to become a member of the
13th Politburo, one of China's top decision-making bodies, which was headed by Yang's old boss Zhao Ziyang as General Secretary. ==Conflicts==
