Life has no algebra, life has geometric sentences.

For example, morning dew is much more difficult to go to Japan. "It's hard to go to the sun if it's morning dew" comes from a short song by Cao Cao of the Three Kingdoms. The original poem is "Life has no algebra, life has geometry, such as morning dew, it is difficult to go to the sky". This sentence compares life to morning dew, which shows that life is short and fleeting, and shows the poet's concept of grasping the present and eating, drinking and having fun in time.
