First frost solar terms taboo

1. Avoid frost-free. In Taicang, Jiangsu, China, there is a taboo that the first frost will not be seen every day. There is a proverb: "The first frost sees the frost, and the rice is rotten." If there is frost before the first frost, the rice harvest will be affected and the rice price will be high.

2. Avoid freezing in autumn, the first frost has entered the late autumn. There has always been a folk saying that "spring covers autumn and freezing", but the temperature difference has changed greatly since the first frost. During the first frost, the temperature difference between day and night is very large. Once the cold wave strikes, the temperature difference between day and night can reach more than 10T. Under the stimulation of cold, the autonomic nervous function of human body is prone to disorder, and the normal law of gastrointestinal peristalsis may be disrupted.
