Preface: It is no doubt that coincide often appears myth stories handed down from ancient times. The coincides is related to the astronomical phenomenon.

Mythological background: Legend has it that since the Northern and Southern Dynasties, the seventh day of the lunar calendar is the day
when Altair(牛郎) and Vega(織女) meet once a year. It is commonly known as “Chinese Valentine’s Day”.
This is a love story that has been passed down through the ages.
Remark: The Northern and Southern Dynasties were a period in Chinese history. From 420 to 589 AD, it was a turbulent era.

Astronomical phenomenon synopsis: The Pleiades, also known as The Seven Sisters and Messier 45, is an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus(金牛座).
Lyra is one of the most brilliant constellations in the northern galaxy, named after the harp shaped like an ancient Greek. It is one of the 48 constellations listed by the ancient Greek astronomer Ptolemy and one of the 88 modern constellations set by the International Astronomical Union. Although Lyra is not large in size, it is not difficult to identify,
because its ruler Vega is one of the vertices of the “Summer Triangle”.

In summer, the summer triangle rises to the zenith in the mid-latitudes of the northern hemisphere. After sunset in autumn, the summer triangle can still be easily seen in the west.

Ref: Since the Tang Dynasty, the Pleiades have been regarded as seven stars. But modern astronomy says this is incorrect.
