Why are peach trees called lucky numbers?

Originated from Peach Blossom Luck, in the long history, a dynasty thought it was a woman's lewd behavior, but there was a poem in The Book of Songs, "Peach Blossoms fly away and burn their splendor", which described the beautiful scene when women got married.

In Zhouyi, "meridian You Mao" represents four directions: due south, due north, due east and due west. When the four elephants meet, the peach blossoms will bloom. At this time, it is best to seek feelings, so people call love "Peach Blossom Luck".
