Why are there no Li He in 300 Tang poems?

1. is related to the selection criteria of 300 Tang poems. There are 300 Tang poems, and Li He's poems are typical of the changes of Tang poems, which deviate from the principle of choosing poems in some aspects.

Li He is called "Shi Gui", and his ghost poems are well written. He can make negative scenes confusing and sad. However, after all, 300 Tang poems are children's enlightenment books, and this style of "the sword is biased" is obviously inappropriate.
