Analysis:

The Tanabata Festival, also known as the Seven Charms Festival, the Seven Sisters Festival, the Daughters' Festival, the Beggar's Festival, the Seven Maidens' Meeting, the Tanabata Festival, the Cow and Cowwoman's Day, the Qixi Festival, and so on, is a traditional festival of Chinese folklore. The Tanabata Festival is derived from the worship of the starry hosts and is traditionally known as the Festival of the Seven Sisters, so it is called Tanabata because the worship of the Seven Sisters is held on the seventh day of the seventh month of the lunar calendar. Worshipping the Seven Sisters, praying for blessings and making wishes, begging for skill, watching the Altair and Vega stars, praying for marriage, and storing water for Tanabata are all traditional customs of Tanabata. Through the development of history, Tanabata has been endowed with the beautiful love legend of "Cowherd and Weaving Maiden", making it a festival symbolizing love, which is considered the most romantic traditional festival in China, and in contemporary times, it has even produced the cultural meaning of "Chinese Valentine's Day".

The Tanabata Festival is not only a festival for worshipping the seven sisters, but also a festival of love, which is a comprehensive festival with the theme of praying for blessings, begging for coincidental gifts, and love, with women as the main body, based on the folk legend of "Cowherd and Weaving Maiden" as a carrier. The "Cowherd and Weaving Maiden" of Tanabata originates from people's worship of natural celestial phenomena. In ancient times, people corresponded the astronomical star area with the geographic area, and this correspondence was called "star dividing" in terms of astronomy and "field dividing" in terms of geography. This correspondence is known as "the division of stars" for astronomy and "the division of fields" for geography. According to legend, every year on the seventh day of the seventh month, the Cowherd and the Weaving Maiden will meet at the Magpie Bridge in the sky.
