"Chu Shu" is the 14th solar term in the traditional Chinese lunar calendar and the last solar term of summer. The term "Chu Shu" literally means "the end of heat," indicating that the intense summer heat is beginning to wane and cooler weather is approaching. It usually falls around August 23rd to 24th when the sun reaches the celestial longitude of 150 degrees.
Here are some key features and customs associated with Chu Shu:
1. Weather Changes: After Chu Shu, daytime temperatures may still be relatively high, but there is a noticeable drop in temperature during the mornings and evenings. The arrival of cooler air masses signals the beginning of autumn.
2. Agricultural Activities: Chu Shu marks an important period for agricultural work. Farmers are busy harvesting crops like rice and corn, and also preparing the fields for autumn planting. The weather conditions during this period are crucial for the maturation and harvest of crops.
3. Traditional Customs:
- Ancestor Worship: In some regions, Chu Shu is a time for people to visit ancestral graves, perform rituals, and pay respects to their ancestors, expressing reverence and remembrance.
- Releasing River Lanterns: People in areas near rivers or lakes may release floating lanterns to pray for peace and good fortune. This custom is linked to folk beliefs in river deities and symbolizes sending off the heat and welcoming the coolness.
- Dietary Adjustments: With the transition in weather, dietary habits are adjusted to cope with the remaining summer heat and the onset of cooler temperatures. Foods that are cooling and moistening, such as lotus seeds, lily bulbs, and white fungus, are commonly consumed.
- Cultural Significance: Chu Shu, like other solar terms, is an integral part of traditional Chinese culture. It reflects the ancient Chinese wisdom of living in harmony with nature and adjusting human activities according to seasonal changes. This concept of harmony between humans and nature is a fundamental aspect of Chinese philosophy.
Chu Shu signifies the end of the hot summer and the arrival of the cooler autumn season. It affects not only agricultural practices and daily life but also carries rich cultural connotations and traditional customs.
