As for praising the prosperity of the Tang Dynasty,
Taizongtu
Big heart, big heart,
Call me Iron Horse.
Read through the ages,
Exclusive in the world.
Controlled by Guan Zhen.
Xiangyun first bloomed,
Poetic and picturesque.
I like letting a hundred flowers blossom,
Laugh and listen to a hundred schools of thought contend.
Among the 300 Tang poems, these two poems mainly praise Emperor Taizong.
You remember the references, right?
