2. Evening Sacrifice, Cow and Bull's Day and Qiaoxi are traditional folk festivals in China. Chinese Valentine's Day, derived from the worship of the stars, is the birthday of the Seventh Sister in the traditional sense. Because the worship of the Seventh Sister was held on July 7th, it was named Tanabata. It is the traditional custom of Qixi to worship the Seventh Sister, pray for wishes, beg for skillful arts, sit and watch the morning glory and the weaver star, pray for marriage, and store water on Qixi. After historical development, Tanabata has been endowed with the beautiful love legend of "Cowherd and Weaver Girl", making it a festival symbolizing love, thus being regarded as the most romantic traditional festival in China, and it has even produced the cultural meaning of "China Valentine's Day" in contemporary times.

3. Chinese Valentine's Day is not only a festival to worship the Seventh Sister, but also a festival of love. It is a comprehensive festival with the folklore of "Cowherd and Weaver Girl" as the carrier, the theme of blessing, begging for skill and love, and women as the main body. The "Cowherd and Weaver Girl" on Tanabata originated from people's worship of natural astronomical phenomena. In ancient times, people corresponded the planetarium and geographical areas. This correspondence was called "dividing the stars" in astronomy and "dividing the fields" in geography. According to legend, on the seventh day of July every year, the Cowherd and the Weaver Girl will meet at the Magpie Bridge in the sky.
