It's easier to see when it's different than when it's gone. What do you mean?

It is easier to see when it is not easy to see, and it is also the meaning of heaven and earth to describe the parting and gathering between people. "It's easy to see when it's easy, but it's hard to see when it's easy, and spring water is exhausted" is a poem written by Du Fu, a poet in the Tang Dynasty. The meaning of this poem is that it is easy to meet each other when parting, but difficult to meet each other. Just like water falling out of flowers, after spring, it will never come back. It expresses the impermanence of parting and time flow in life, and the importance of cherishing the present. This poem is also often used to describe the feelings of parting and gathering between people.
