(The Story of China's Reform & Opening Up---Designed in China)

The History of China's Scientific and Technological Development

Stage 1: In the ancient times, China had many firsts.

Great inventions which powered the modern world are              ,             ,              , and the                                , indicating that Chinese civilization always gave importance to science and technology.

Stage 2: In modern times China                      the west, especially in the period of the Cultural Revolution in the 1960s and 70s. 

Stage 3: After 40 years China began to get back to the top with huge resources invested

♦40 years ago China was still in its first                  age when China had fallen far behind. The top speed for Chinese trains was               kph, standing in sharp contrast to Japan's Shinkansen travelling at                 kph.

♦Through the 1980s technological development in China moved                 from installing mainframe computers to rocket science. 

♦In the 1980s and 90s electronics was at the heart of China's technology                  with Shenzhen being the centre and the largest electronics market. But China's developing high-tech industry was based on                technology and parts and cheap                 labours doing the processing and assembling for export.

♦In 2002, focus was                   to a smaller cluster of technologies and began to promote                      innovation. Instead of copying the imported                  and technology, the Chinese learned by doing and put it to work.

♦In 2014, the focus was widened to the entire                    process, not just in technology, but also in modern services and in traditional industries like railways. Only 10 years since we introduced                      technologies, we can now entirely and                    develop, design and build high-speed trains.

♦By 2025, China aims to be                    in traditional technologies, and its next goal is to be at the cutting edge in the development of new technologies through forming                   between high-tech companies and research institutes and universities like SUSTech in Shenzhen with the emphasis on                     and                    .

Stage 4: Today such huge firms as Huawei, DJI and Tencent are flexing their muscles on the world stage, looking forward to the fourth industrial age, that is, AI. China seems to be well                   to be one of the two leaders in artificial intelligence due to its                  to big data.
