Stars.
Du Fu in the Tang Dynasty wrote a poem in "To the Eight Virtues of the Guard": "If we don't meet each other in life, our movements are like participating in business." "Participating in business" refers to the stars. If we don't meet each other in life, our movements are like participating in business." The "Shen" and "Shang" in "Shen" and "Shang" refer to the stars. Shen star lives in the west and Shang star lives in the east. They each occupy one side. One star rises and the other sets, and they can never meet each other. .
Participating in Shang is the name of the stars in the Middle Ages. Du Fu’s poem means that people are like the ginseng and Shang stars in the sky. Once they are separated, it is difficult to meet. .
