Three inches of time has no name.

Three inches of time, live up to youth.

Time originally refers to light and dark, day and night. By extension, it means the passage of time between the sun and the moon.

In ancient times, time represented time. Time is divided by people according to material movement, not inherent. There is no time in the universe. Material movement takes time,

But if we don't divide "time" into spaces, our thinking can't recognize "time". The reason why we can think is that thinking can name the material world, while things are real, thinking is empty, and thinking about life and things is empty. An undivided "time" cannot be named and distinguished. Only by dividing it into "time" can it be used by thinking, because it can only be named after division. For example, we divide the earth's movement around the sun into one year and the earth's rotation into one day, which is convenient for thinking to calculate with digital symbols. If you don't live on the earth, you will never divide time by the movement of the earth. Therefore, time is only a division of material movement for the convenience of thinking about the universe. This is a man-made rule, not a natural rule. The room is artificially divided, so you can divide it at will.

Time exists objectively. The concept of time is the result of human understanding, induction and description of nature. In ancient times, its original meaning originally referred to the change of seasons or the reincarnation of the sun on the ecliptic. "Shuo Wen Jie Zi" says: It is four o'clock; "Guanzi Shanzhong" said: When, so remember the year. With the deepening of understanding, the concept of time covers all tangible and intangible movements. There is a comment in the preface to Mencius: "It is said that time is also a branch of the five elements." Visible tense is used to describe the unified attribute of all sports processes, which is the connotation of tense. Because the problems studied by the ancients are basically macroscopic, rough and slow-paced, and only pay attention to the problem of "time". Later, the concept of "time" was added to study fast and instantaneous objects. Thus, time covers the continuous state and instantaneous state of the movement process, and its connotation is finally enriched and perfected, and the word "time" is finally finalized.
