Who knows the pinyin of Li Shangyin's February 2 poem? It's different from our modern pronunciation! Are there any modal particles?

Yue (Xu)

Wind (wind sound) (level)

Xu (xu 1) (Ping)

Butterfly (Butterfly 4) (Wrong)

Li (Li Sheng) (Xu)

Year (year tone) (flat)

Beach (tan 1 sound) (flat)

Left (left)

Among them, "butterfly" is an ancient entering tone word. If you still don't understand anything, you can leave me a message. I have specially studied the ancient entering tone characters.
