Please give me an ancient poem describing fog and two poems praising snow. Thanks in advance.

The ancient poem describing fog said: "The fog is three mornings away, and the dark city is five miles dark." Here are two allusions to fog. According to the records of emperors, the Yellow Emperor was foggy for three days. According to the Records of the Later Han Dynasty, Zhang Kai was good at Taoism, and he was able to create five-mile fog. Poems about objects often quote related stories to make the words more elegant. The meaning here is nothing more than that the fog is heavy, lasts for a long time and spreads widely. The following is a detailed description of fog.

"Snow is too late for spring, it is a flying flower on the courtyard tree." These are two poems about snow written by Han Yu, a poet in the Tang Dynasty, which are translated into vernacular Chinese: snow is too late for spring, and it deliberately turns into flowers and flies among trees in the courtyard.

The full text of the poem is: there is no fragrance in the New Year, and grass buds are first seen in February. Snow is too late for spring, and it is intended to fly for the flowers on the courtyard trees.

This poem was written in August15 (Yuan and Ten Years) and written by Han Yu in Renchao History Museum. For Han Yu, who has been to Lingnan, the spring in the north comes a little late, and the grass shoots don't grow until February, so the author draws lessons from Cen Can's Bai Xuege and writes this poem.
