Please point out the beat of Jiang Xue.

There are no birds flying over those mountains, and there are no traces of people in those paths. A boat on the river, a fisherman wearing his webworm moth; Fishing alone is not afraid of snow and ice.

Flat and light, flat and light. Flat and flat, flat and flat.

Generally speaking, Yin Ping and Yang Ping's tone is flat, losing the high-pitched tone. The "Jue" and "Du" in this poem belong to the entering tone in the ancient rhyme and have been lost.
