Tomb-Sweeping Day planted willow and wormwood on Dragon Boat Festival, which reflected the biological impact?

This situation reflects the influence of temperature on living things.

This agricultural proverb shows that the growth and change of plants will be different in different solar terms. During the Qingming Festival, the temperature rises gradually and willows begin to sprout and grow. People will insert willows at this time. During the Dragon Boat Festival, the temperature rises further and wormwood grows vigorously. At this time, people will insert wormwood. This shows that the growth and change of plants are regulated and influenced by solar terms.
