In March 1981, Yuan Geng, head of the Shekou Industrial Zone in Shenzhen, wrote the slogan “Time is money, efficiency is life.” It brought him heavy criticism. Critics called him “a capitalist who wants money and lives” and spoke of “the restoration of capitalism.” The giant billboard was put up in Shekou and taken down several times.
In January 1984, Deng Xiaoping endorsed the slogan on his first visit to Shenzhen. On October 1, 1984, it rode past Tiananmen on the Shekou float in the National Day parade.
