In what season are red leaves everywhere?

It's autumn, and the mountains are covered with red leaves. Autumn is the harvest season, and many plants mature in autumn. In nature in autumn, the qi of Yin and Yang begins to change, the yang gradually declines, the yin gradually grows, the climate turns from hot to cold, and everything is born with cold, which is the season of alternating cold and heat.

Entering autumn means rain, storms, etc. Tending to decline or decrease, everything in nature began to mature from luxuriance. The beginning of autumn doesn't mean the end of hot weather. The so-called hot weather is in dog days. According to the calculation method of dog days, beginning of autumn is often in dog days until the heat, so the weather is still very hot in early autumn, and it will generally cool after the Millennium solar terms.
