It originated in China and is a traditional festival in China and East Asian countries. The festival comes from the legend of the Cowherd and the Weaver Girl, and is celebrated on the seventh day of the seventh lunar month (after the Meiji Restoration, it was changed to the seventh day of July in the Japanese solar calendar). Because the main participants in this day's activities are girls, the content of the festival activities is mainly begging skills, so people call this day "begging skills festival" or "girls' day".
Valentine's Day in China originated in the Han Dynasty. In the Miscellanies of Xijing written by Ge Hong in the Eastern Jin Dynasty, it is said that "women in the Han Dynasty often wear seven-hole needles on the seventh day of July, and everyone is ambitious." This is the earliest record of begging for wisdom in China ancient literature. In the Tang Dynasty, Wang Jianyou wrote a poem: "Stars adorn pearls, and Gong E is busy on Qixi"; "The Legacy of Kaiyuan Tianbao" contains: Every time Emperor Taizong and his concubines held a banquet in the Qing Palace on Tanabata, the ladies-in-waiting begged with their own ingenuity, and this custom continued among the people for a long time.
