How to evaluate setting the annual lunar vernal equinox as "China Farmers Harvest Festival"?

From the perspective of solar terms, spring planting and autumn harvest, Chunhua Qiushi, and the autumn equinox season are fruitful, which can best reflect the bumper harvest. In addition, the autumnal equinox, as one of the 24 solar terms, is equally divided day and night, and the autumn is crisp. It is not only an important season for autumn harvest, autumn ploughing and autumn planting, but also a good season for rice fragrance, crab fat and chrysanthemum yellow and autumn scenery. Geographically, China has a vast territory and rich products, and the harvest season varies from place to place, but most places are autumn, and the autumn harvest crops are big. Therefore, considering the north and south, the autumnal equinox is designated as "China Farmers Harvest Festival".
