1, the Millennium solar term means that the weather turns cold. Millennium is the fifteenth of the twenty-four solar terms, and the date is from September 7th to 8th every year. Millennium is a solar term after the summer heat. Although it will be sultry in the hot summer, it will turn cold quickly in the Millennium, with a large temperature difference between day and night and light rain.

2. The customs of Bailu solar terms include offering sacrifices to Yu Wang, eating sweet potatoes, eating longan, drinking Bailu rice wine and drinking Bailu tea. The reason for worshipping Yu Wang in the Millennium is that in the Ming and Qing Dynasties, Dayu was called the "water god", so every Millennium, fishermen would come to worship him and pray for a bumper harvest in the coming year. The custom of "eating longan" comes from Fuzhou, Fujian, China. Because longan has the effect of invigorating qi and strengthening the spleen, people think that eating longan on the day of the Millennium has a great nourishing effect.
