For scholars, time means: "An inch of time is worth an inch of gold, and an inch of gold cannot buy an inch of time." Only by cherishing time can scholars create their own value and open up a new world of knowledge for the development of human civilization. Only by further developing science and technology can we contribute our talents to the development of our motherland. On the contrary, if you do not cherish time and live a mediocre life, tomorrow after tomorrow, you will not only ruin your own future, but also bring economic losses to the country.
