I heard that the 7th of this year is breakup day?

Tanabata is the "breakup festival" of the ancients. Long, long ago, the Cowherd and the Weaver Girl were actually the inevitable symbol of breakup for ancient lovers.

In 1970s, archaeologists excavated a batch of bamboo slips in A Qin Dynasty cemetery in Hubei Province, some of which were called "Japanese books" (the notes of leaders, which were not diaries of ancient people, but yellow calendars recording daily taboos). The record about the Cowherd and the Weaver Girl on Tanabata turned out to be the wedding anniversary: Ji Youwu pulled the cow and married the Weaver Girl, failed and abandoned it three times; Ji You's Wu Shen took the cow to marry the Weaver Girl, but it didn't work. If the Weaver Girl is less than three years old, she will abandon her.

These two days' WuShen and Ji You may reveal that the ancient people were very taboo to get married, because the Cowherd married the Weaver Girl three times, but abandoned the Weaver Girl three times, which indicated that the marriage was unhappy.
