清明时节雨纷纷，路上行人欲断魂。

The drizzling rain falls heavily at the Qingming Festival, and the travelers on the road feel as if their souls are about to leave their bodies.

借问酒家何处有，牧童遥指杏花村。

Asking the way to the Wine-house, the shepherd boy points to the Apricot Flower Village in the distance.

北风卷地白草折，胡天八月即飞雪。

The north wind blows over the white grass, breaking it. The snow flies in the sky of the eighth lunar month.

忽如一夜春风来，千树万树梨花开。

Suddenly, like a spring breeze, thousands of pear trees burst into full bloom.

散入珠帘湿罗幕，狐裘不暖锦衾薄。

The rain falls onto the pearl curtains, wetting the silk curtains. The fox fur coat is not warm enough for the thin silk quilt.

将军角弓不得控，都护铁衣冷难着。

The general's horn bow cannot be strung, and the iron armor of the commander is too cold to wear.

瀚海阑干百丈冰，愁云黯淡万里凝。

The hundred-foot ice in the vast sea is like a barrier, and the clouds of sorrow gather and darken the distance.
