The seventh day of the seventh lunar month in China is a folk begging festival in China. It is said that this day is also the day when Altair and Vega meet in the sky. On July 7th, the girls wanted to "please" the Weaver Girl. They brought colored thread and seven needles. If it can pass smoothly, it is a girl with excellent skills. It is said that children can still hear cowherd and weaver girl whispering under the grape trellis that night.
