"Smell" is a season that reflects phenology. It was the first ten days of March in the solar calendar, and the weather was getting warmer and the spring thunder began to shake. Hibernating animals and various insects in dormant soil feel warm and shocked in spring. In this festival, the land in northern Shandong is completely thawed from September 9 to September 9, with the temperature generally at 4 ~ 5℃ and frequent cold waves. Maximum temperature 18 ~ 23℃, minimum temperature -3 ~ 7℃. The precipitation is generally 3 ~ 5 mm, sometimes more than 20 mm, and sometimes less than 1 mm.

In this season, the phenomenon of "cold spring" in the south of the Yangtze River will last until the last few days of fright, while the cold climate in the north will last longer, so "spring cover" is still very important in this solar term. Especially for the elderly, don't cut too little clothes just because the weather is getting warmer this solar term. Clothes should increase or decrease with the climate change. At this time, the liver qi is strong, and the elderly are prone to get angry. Pay attention to the adjustment of mood and consciousness, keep calm at any time, and don't get angry, otherwise the liver qi will rise too much, which is easy to dizziness and stroke. This solar term should be washed with medlar soup to keep the skin shiny.
