What poems are used to compare the four geographical regions of China?

Northern region: The north wind rolled white grass and blew it to pieces. Eight In the snow crossed the Tatar sky. Suddenly, like a night wind blowing, like a pear tree in bloom.

Southern District: Ti Ying is a thousand miles green, and the water town is full of wine flags.

Northwest: The Yellow River is an isolated city, Wan Ren, far above the white clouds. Why use the elegy of willow to complain about the delay of spring, old Yumenguan, a spring breeze is not blowing!

Qinghai-Tibet region: hunting tianjiao outside Juyan city, burning white grass in the wild, driving horses when the sky is cloudy, and hiding autumn carvings in the plain.
