Who knows what kind of Buddha this is?

This is not a Buddha, this is the head of a bodhisattva.

The Buddha's head is easy to recognize, that is, the Buddha is a bun, which means that the Buddha's hair is a small curly hair that curls to the right. This portrait with hair should not be a bodhisattva or a Tang priest, because these two perspective images, that is, the bald one without hair, have hair, and the pilu hat worn by Tang priest is a celestial crown, so it should be a Buddha statue. It may be the head of Guanyin Bodhisattva or Manjusri Bodhisattva. But it's definitely not a Buddha's head, nor is it a Tang priest.
