As far as melody is concerned, what kind of poem does Delighting in Rain on a Spring Night belong to?

This poem is a five-character poem. The following is a metrical analysis:

Good rain knows the season, when spring comes. Flat and light, flat and light. ("Jie" and "Fa" are Rusheng, but they are not)

Sneak into the night with the wind, moisten things silently. Flat and light, flat and light. ("dive" is awkward, this posture should be flat, but no matter 135, it won't work. )

The wild path is dark, and the river is bright. Flat and light, flat and light. ("all" is a flat and even word, which is Zhu Qi; "Independent" is the entering tone word)

Look at the red and wet place, the flowers in Jinguancheng are heavy. Flat and light, flat and light. ("Look" is a flat voice; "Wet" is the entering tone word)

The whole poem is in quadruplicate, each couplet is "positive" and both couplets are "sticky", which is a metrical poem.
