Let's talk about why heaven and earth are so powerful.

Heaven: Pun, white refers to the Heavenly Palace, actually refers to the palace.

How many times: several times. It means that it is rarely heard in the world. How many times can you hear it in ordinary people's homes?

It's daydreaming to brag about the fairy music in the sky. Because of reality and emptiness, the reality and reality are born together, and the beauty of music is praised to the extreme.

However, this is only a literal meaning, and the implication is meaningful. This can be seen from the words "heaven" and "earth". "Tian" actually refers to the palace where the son of heaven lives; "People" means outside the palace. This is a common pun in feudal society. It is said that music belongs to the sky, and the word "should only be" has been added. Since it is "should only be in the sky", then "people" should certainly not be "hearing". Don't "smell" but "smell", not only "smell several times", but also "day after day", so the author's satire is both implicit and witty and accurate from this contradiction.
