The great achievements of the motherland

1. In terms of scientific and technological research, in 1964, China successfully developed its first atomic bomb and successfully tested it. On October 8, 1956, China’s first rocket and missile development institution, the Fifth Research Institute of the Ministry of National Defense, was established. On April 24, 1970, China's first artificial satellite flew into space singing "The East is Red", which started the process of China's aerospace technology.

China became the fifth country in the world to launch satellites. In 1979, the "Yuanwang" 1 space survey ship was completed and put into use, making China the fourth country in the world to have an ocean-going space survey ship. In May 1980, the launch of a large launch vehicle into the Pacific Ocean marked that China's launch vehicle technology had reached a new level. China has successfully developed four types of Long March series rockets including Long March 1, 2, 3 and 4.

2. In terms of agricultural technology, China is a major agricultural country. The research results of Yuan Longping, the father of hybrid rice, not only solved the problem of feeding the Chinese people, but also made outstanding contributions to reducing hunger in the world.

3. In terms of industrial technology, in July 1957, Kunming Machine Tool Factory successfully trial-produced China's first high-precision electric coordinate boring machine. In June 1958, Changchun No. 1 Automobile Manufacturing Plant successfully trial-produced China's first domestically produced luxury sedan. In April 1961, Shanghai Jiangnan Shipyard successfully manufactured China's first 10,000-ton hydraulic press. Through a 61-year historical process, China has now entered some of the world's leading industries in industrial technology.

4. In terms of communication technology, in December 1983, the Computer Research Institute of the National University of Defense Technology developed a large-scale computer system named "Galaxy". Since then, China has entered the ranks of the world in developing supercomputers. In 2010, China successfully developed the world's fastest large computer, Tianhe-1.

Major changes in the motherland:

Reform and opening up, reform and opening up, have made China build a new countryside faster and faster. More and more rural people are going to middle schools and universities and have become a new generation of think tanks in building the motherland; mobile phones, color TVs, refrigerators... things that were once unthinkable have become a reality. In the past, rural areas gave people the impression of being dirty and messy.

When it rains, the path becomes a "dirt road"; the mountains are overgrown with weeds and no one cares. Now, the government has ordered roads to be repaired and rural infrastructure has been greatly improved. Reform and opening up have brought vitality to rural areas and made people's lives happier.
