Please help me find 3 ancient poems about deserts and draft a slogan about "protecting the environment"

1. If you want to ask about the side of a bicycle, the country you belong to is too long.

Zheng Peng left the Han Dynasty, and returned to the Hutian.

The lonely smoke in the desert is straight, and the sun is setting in the long river.

When Xiao Guan is waiting to ride, he will protect Yan Ran. "The Envoy to the Fortress" by Wang Wei of the Tang Dynasty

2. The desert is windy and dusty, the sun is dim, and the red flag is half-rolled out of the camp gate.

The former army fought in Taohebei at night and reported that Tuyuhun was captured alive. Changling, King of the Tang Dynasty, "Walking in the Army"

3. If you don't see me, you are walking along the horse river on the snowy seaside, and the flat sand is vast and yellow. The wind roared on the September night in Luntai, and the gravel in the river was as big as a bucket, and the stones were scattered all over the ground in the wind. The Xiongnu grass is growing yellow and the horses are getting fat, smoke and dust are flying in the west of Jinshan Mountain, the generals of the Han family are marching west, the generals don’t take off their golden armor all night, the troops are fighting each other in the middle of the night, the limelight is like a knife cutting the surface. The horse hair is steaming with snow and sweat, the five-flowered money is swirled into ice, and the grass and inkstone in the curtain are condensed with water. The captive cavalry should be frightened when they hear this. They know that they are short and they are superior and dare not accept it. Military advisor Ximen stands still to show his victory.

Tang Cen Shen's "Walking Horse and River to Send Doctor Feng to the Western Expedition" Slogan to protect the environment---the environment connects you and me, and cleanliness and protection rely on everyone

Environmental protection belongs to everyone responsibility.

Green the world and benefit tomorrow; the environment and human beings coexist, and development and protection are synchronized
