We young people must have a better view of the afterwave than today's young people, because human beings are developing, society is progressing and various scientific frontiers are constantly innovating. The waves behind the Yangtze River push forward the waves, and China has developed from a poor country to a powerful country, and the people's living standards have reached a well-off level. This is inseparable from the successors, and it is also inseparable from the diligence, hard work and study of you young people, and you will always climb the peak of science. For example, the rapid development of the media industry in China is the result of your young people's efforts. For example, the success of 5G research on mobile phones and the future 6G, 7G, 8G, etc. You need the back wave to push the front wave, so the wisdom of the back wave is infinite. The peak of science needs successors and needs to be climbed forever before the country can develop and grow.
