Tanabata, formerly known as Begging for Cleverness Festival. The Qixi Festival, which originated in the Han Dynasty, is recorded in Gehong's Miscellanies of Xijing in the Eastern Jin Dynasty that "the women in the Han Dynasty often use the seven-hole needle on the stone relief in the Han Dynasty on July 7 to open the front floor, and everyone is Xi Zhi".
According to historical documents, at least three or four thousand years ago, with people's understanding of astronomy and the emergence of textile technology, there were records about Altair Vega. People's worship of stars is far more than Altair and Vega. They think that there are seven stars representing directions in the east, west, north and south, which are collectively called Twenty-eight Nights, of which the Big Dipper is the brightest and can be used to tell the direction at night.
The first star of the Big Dipper is called Kuixing, also known as the champion. Later, with the imperial examination system, the champion in the middle school was called "Dakui Tianxia Scholar", and the scholars called Tanabata "Kuixing Festival", also known as "Book-drying Festival", keeping the trace that the earliest Tanabata originated from the worship of the stars.
