What is the constellation of Ximen Qing?

Ximen Qing's date of birth and constellation.

There is no direct record of Ximen Qing's date of birth in Jin Ping Mei (perhaps I missed it when I was reading), so I will not hesitate to infer the date of birth of Wu Er and Pan Shi with pen and ink, thus indirectly researching the date of birth of Ximen Qing. In the fourth time of the original work, the woman asked Ximen Qing about his seniority, and Ximen Qing told him, "I am 27 years old and was born on July 28th." It has been verified in the previous article that when Ximen Qing asked Pan Shi's age for the third time, Pan Shi replied with her real age, and Ximen Qing soon knew her zodiac sign. There was no misunderstanding between the two sides on this point. Then when Ximen Qing answers Pan Shi, he should also use his real age. He is two years older than Pan Shi and was born on July 28th of the first year of Yuanyou. This day is September 6th. 1086. Maid in waiting

But we can't completely rule out the possibility of "nominal age" as Ximen Qing said. For example, in local folklore, life expectancy is "full for men and full for women", men are nominal years old and women are real years old. Suppose Ximen Qing says that 27 years old is a nominal age, he should have been born in Yuan You on July 28th, 2002, that is,1August 28th, 087. Or virgo.
