Why did the first apricot blossom bloom in Tomb-Sweeping Day?

This is not the first apricot blossom in Tomb-Sweeping Day. According to the relationship between temperature and sunshine, the flowering period of apricot flowers is from March to April, and the flower shape is similar to that of peach blossom and plum blossom. It is pure red in bud, gradually fades after flowering, and becomes pure white when falling. The fruit period is from June to July, and the flesh is dark yellow, sweet and juicy, with suture and pilose, light yellow to yellow red.

Apricot flowers are solitary with open leaves and white or reddish petals. They are famous ornamental trees in China. Apricot flowers are characterized by discoloration. They are bright red when they are in bud. As the petals stretch, the color gradually changes from thick to light, and turns white when falling. "The white road is not really white, and the scarlet letter is not red. Please red and white, don't look at nature. " This is the Song Dynasty poet Yang Wanli's careful observation of apricot flowers.
