On this day, 39 years ago, on May 10, 1986 (April 2, 1986, the lunar calendar), Deng Xiaoping talked about two "doubling". On May 10, 1986, Deng Xiaoping, director of the Central Advisory Commission, met with Canadian Prime Minister Brian Mulroney in Beijing and said that it now seems that by 1988, it is possible to double the annual total industrial and agricultural output value of 1980, laying the foundation for doubling again by the end of the century. He said that the first doubling will be achieved by opening up to the outside world and invigorating the country internally, as well as by the success of rural reform. The second doubling depends on the success of urban reform. The current urban system reform is actually a comprehensive system reform, which also includes education, science, etc. The "Seventh Five-Year Plan" does not pursue excessive development speeds. The main goal is to achieve urban system reform. Now it seems that the momentum is good.
