Which month does the solar term Xiaoyangchun refer to?

For a long time, China used the "summer calendar" to call 1 1 month as the beginning of the year. Traditionally, 1 1 month is called "Xiaoyangchun".

In the early winter, the bell rings in Yue Ji, Liang Yue, Kunyue, YueYang, Xiaoyangchun and Haiyue, so Xiaoyangchun refers to October of the lunar calendar, which is only one month.

In some areas of our country, the climate of this season is called the habit of "Koharu in October", which means that some fruit trees will bloom twice during the winter solstice and the light snow festival, showing the same warm weather in spring as in March.
