1. Autumn is the season when all things ripen. The weather becomes cool, winds strong, earth clear, and all things change color.
2. People should go to bed early at.night and get up early at daybreak like the rooster, to keep your mind comfortable and calm.
3. This will allay the effects of the cool weather on the body so that we can preserve our vital qi and keep it in balance.
4. This is why we should preserve qi for autumn. Otherwise, lung qi will be harmed. One will suffer from persistent diarrhoea in winter and the ability to suit winter will be weakened.
