Has the weather started to get cold in the autumn equinox and solar terms?

The autumnal equinox is on September 23rd in the solar calendar and August 5th in the lunar calendar. The day is as long as the night, which is twelve hours. From this day on, the days are getting shorter and shorter. This is the vernal equinox solar term. With less sunshine, the weather will naturally get colder every day. Since the vernal equinox, the weather has turned cold. At that time, I will begin to understand: "One autumn rain is cold, and ten autumn rains need to wear cotton."
