Is it still cold after 69 days?

6: 00 is beginning of spring season, and the climate is characterized by large temperature difference between day and night and frequent cold air activities. So I still feel cold, especially at night.

Jiujiu, also called Jiujiu in winter, is a folk method to calculate the date of warm flowers in spring and cold days in China. Generally, March and April are the coldest time, which is the coldest time of the year. When you count to nine "nine days" (998 1 day), spring will be deep and warm, and everything will be full of vitality. It's time for spring ploughing. Common Jiujiu songs are: 1929 Don't shoot; Walking on the ice in 3949; 5969 see willows along the river; 79 rivers open 89 geese; 99 plus 19, plowing cattle everywhere.
