Valentine's Day in China, which originated from the worship of stars, is Seven Sisters's birthday in the traditional sense. Because of the worship of Seven Sisters on the seventh day of July, it was named Tanabata. This is a traditional folk festival in China.

Valentine's Day in China is not only a festival to worship Seven Sisters, but also a festival of love. It is a comprehensive festival with the folk custom of "Cowherd and Weaver Girl" as the carrier, with the theme of blessing, begging and courtship, and women as the main body. The "Cowherd and Weaver Girl" on Tanabata originated from people's worship of natural phenomena. In ancient times, planetariums were associated with geographical areas. This correspondence is called "dividing stars" in astronomy and "dividing fields" in geography.
