Ni Zhifu

Ni Zhifu was a Chinese engineer, inventor, and high-ranking politician. When he worked as a technician in the 1950s, he invented the "Ni Zhifu drill" which earned him a patent and the honour of "model worker". During the Cultural Revolution, he was elevated to leadership positions in the municipal government of Beijing and became an alternate member of the Politburo. He was not close to the Gang of Four, and for that reason his career continued to rise when the Gang fell at the end of the Cultural Revolution in 1976. He became a full member of the Politburo, and served as Deputy Communist Party Chief of Shanghai municipality, Chairman of the All-China Federation of Trade Unions, Party Chief of Tianjin municipality, and Vice Chairman of the National People's Congress.
