Every morning in winter, what is the name of the morning star in the east of the moon, basically in Tounan (Zhengzhou), right now.

The answer is shown above, Jupiter, translated into Chinese-Jupiter. Before sunrise, it was located in the southern sky, east of the moon, and its brightness was extremely remarkable, completely in line with the description of the landlord.

However, there are two errors that need to be corrected:

Venus is a proper noun, especially Venus and Morning Star. Even if other celestial bodies move to this position, they can't be called this (literary usage will not be elaborated for the time being). And from the description of the landlord, the first reaction is that it can't be Venus, because its orbit is inside the earth, so it will always be the sun's small partner.

Every winter morning, well, yes, from this year, even a year or two ago, this conclusion is also true. However, when I first saw the starry sky, Jupiter was in Libra (spring of 2006), a constellation at the turn of spring and summer. Eight years have passed, and Jupiter has gone through more than half of the cycle, so it came to Cancer at the turn of winter and spring.
