What does the first poem describe about spring in Sichuan?

Send Serina Liu to Shu.

The pink ones are even green, which is very noisy. Bamboo sacrifice in Yi people's temple, Shu bird milk tung flower.

Wine reports new scenery, and the piano welcomes the gorge. It's not like the end of the world to hear more tourists.

This is a poem by Sikong Shu in Tang Dynasty.

————————————

I wrote about the city walls (powder walls), people (thousands of families) and Yi people (local ethnic minorities, offering bamboo sacrifices at temple fairs-a sacrificial activity) in Sichuan in spring.

Also wrote Shu birds, tung flowers and so on.

In Si Kongtu's "Send Serina Liu to Shu", there is a sentence like "Tung flowers can feed birds, and bamboo joints compete with gods".
