Mathematics of ancient poetry: 1, a trip of two or three miles, four or five smoke villages. The pavilions are six or seven, and the flowers bloom in eighty or ninety. Two, one by one, three, four, five, six, seven, eight. 3, one to two or three miles, four or five smoke villages. The pavilions are six or seven, and the flowers bloom in eighty or ninety. 4, a boat, a silk hook. Sing a song, drink a bottle of wine, and catch a river alone. 5, two orioles singing green willows, a line of egrets on the sky. My window framed the snow-covered western hills. My door often says "goodbye" to ships sailing eastward.

2. Hope of Spring

Tang Dynasty: Du Fu

Chang' an fell, the country was broken, and only the mountains and rivers remained; Spring has come, and the sparsely populated Chang' an city is densely forested.

Sad state, can not help but burst into tears, amazing birds, leaving sorrow and hate.

The war lasted for more than half a year, and letters from home were rare, with a hundred thousand gold.

Twisting with melancholy, scratching my head and thinking, the more I scratch my white hair, I can hardly insert a hairpin.

Chang' an fell and the country was broken, leaving only mountains and rivers; Spring has come, and Chang 'an, which is sparsely populated, has dense vegetation.

Sentimental state affairs, tears can't help splashing, birds are heart-pounding, which only increases sadness but not hatred.

The continuous war has lasted for more than half a year, and there are few letters from home. A letter is worth twelve thousand gold.

Worried, scratching my head, my white hair is getting shorter and shorter, and I can't insert it.
