"For more than a decade before the Cultural Revolution, no one had greater responsibility for building and administering the old system than Deng Xiaoping. During his three and a half years in the countryside from 1969 to 1973, no one who had held high positions had thought more deeply about what went wrong with China's old system and what needed to be done than Deng Xiaoping ... He would open the country wide to science, technology, and management systems, and to new ideas from anywhere in the world, regardless of the country's political system." (Quoted from book)
