Twenty-four solar terms, flowers and letters, summer articles

I read twenty-four letters of Zhang yesterday, originally referring to the corresponding festivals. The so-called harmonious climate refers to the 24 solar terms in a year, and the weather is the work and rest of the gas. One interest for fifteen days, one interest for five days, and each interest includes three classes. Twenty-four letters, from slight cold to Grain Rain, four months. There are eight seasons in these four months, and each season has a flower corresponding to the wind letter, indicating the course and change of the festival.

When I read this, I remembered Ruyi's love in the palace. For example, Ruyi once wrote a poem about Haitang, Pear and Mulan, but it was the vernal equinox.

A small solar term shows the wisdom and good life of the ancients.

Today's light snow, there are three waits, and once the rainbow is gone; In the second quarter, the weather rose, the atmosphere dropped, and in the third quarter, it became winter.
