Li Xu looked at the engrossed audience below and continued, "I wonder, do any of you enjoy flying kites? There's wind in both spring and autumn,
but relatively few people fly kites in autumn, while many do in spring.
Moreover, experienced kite-flyers know that it's harder to get a kite airborne in the fall.
This is precisely because the qi of spring is ascendant, carrying the kite upward;
while the qi of autumn is descendant and contracting, so a kite naturally won't fly high."
"Winter is cold, and all living things wither. Everything conserves its energy to the extreme to reduce consumption. Therefore, the characteristic of winter is 'storage'."
Li Xu gave another everyday example: "We've all probably eaten pork.
In the past, when pigs were raised in the countryside, they were generally raised for a full year and only slaughtered for the Lunar New Year celebrations.
The pork from that time, whether stir-fried or stewed in soup, was exceptionally fragrant and delicious.
