What are the three stages of the autumnal equinox?

There are three stages in the autumnal equinox: the first stage when thunder stops, the second stage when insects sting households, and the third stage when water dries up. The ancients thought that it thundered because the yang was strong and the yin began to flourish after the autumnal equinox, so it stopped thundering. Some insects unearthed at the vernal equinox will return to the soil after the autumnal equinox to prepare for winter. Water vapor is not so rich, it will start to dry up gradually, so the air is getting drier and drier.

The equinox means "equal share" and "equal share". In addition to being divided equally between day and night, autumn has another meaning of being divided equally. After the autumnal equinox, the position of direct sunlight moves south, and the days in the northern hemisphere become shorter, the nights become longer, the temperature difference between day and night increases, and the temperature drops day by day.

The characteristics of rapid cooling in autumn make "Sanqiu solar terms for health" particularly tense in the busy autumn harvest, autumn ploughing and autumn planting. The autumnal equinox is a good time to harvest cotton and tobacco leaves from green to yellow. Winter wheat has been planted in North China, and the Yangtze River basin and vast areas in the south are busy harvesting late rice and ploughing the land to prepare for rape sowing.

When the autumnal equinox comes, eggs are beautiful. In ancient legends, the day of the autumnal equinox is the easiest day to lay eggs. According to historical records, the tradition of dividing eggs in autumn originated in China 4000 years ago to celebrate the arrival of autumn. Oviposition reflects people's reverence and reverence for life and fertility.
