People are inhuman, things are not things, they come from the wind and go in the rain. When they come, they really go to time and space ... What book is it from?

I don't know which book "people are inhuman, things are not things." They came in the wind and went in the rain, and when they came, they really went to time and space, like a mirage, or just a sentence written by others, just quoting the "impermanence principle" of Buddhism. Everything is impermanent. Are changing and moving. Whether people or things, in Zhuangzi's words, there is no land. In addition, Bai Juyi also has a similar poem, "Flowers are not flowers, fog is not fog, come at midnight, go at dawn, come like a spring dream, go like a cloud without finding a place."
