The story of Cowherd and Weaver Girl was formed in the late Eastern Han Dynasty. The Han Dynasty was the period when China feudal society initially completed centralization. The contradiction between the ruling class and the working people is increasingly acute, and people yearn for a self-sufficient life, so there is a description of the free and happy life of the cowherd and the weaver girl after marriage. But at that time, the society was in turmoil and the people's ideals were difficult to realize. The thought and behavior of the Queen Mother reflected the cruelty of feudal forces and the oppression of the people, which led to the plot that the cowherd and the weaver girl lived far apart and could only meet once a year. The story praises the working people's spirit of resisting feudal oppression and striving for freedom and happiness, and reflects their yearning and pursuit for a better life.

Altair and Vega:

Looking up at the starry sky in autumn night, we can see the two brightest stars on both sides of the Milky Way, namely Altair and Vega. Altair and Vega seem to be just "separated by a water", but they are far apart. The two stars are about 16 light-years apart. They are all stars like the sun. The two stars are in the same position, and there will never be a chance to meet.
