What constellation is Li Shangyin?

Shang Yin was born in Feng Hao's eighth year (8 13) and Zhang Caitian's seventh year (8 12). This is what scholars usually use today. Most scholars agree with what Feng Hao said, the most important of which is what he said in the anthology Book of Last Week: "Your Excellency Zhong Cheng: The rest of my life will be 25 years." Inscription: "In December of the first year of Kaicheng, Ji took Cui Guicong, a calligrapher from China, as the guardian of Huazhou, and was also an imperial historian." The book was written in the early spring of the second year of Kaicheng (837), and the poet was twenty-five years old. Based on this, Shang Yin was born in Yuanhe eight years. As for the year of death, it is especially necessary to distinguish the whereabouts and creation of poets in their later years. I don't even know when I was born. Where is the constellation?
