It's upstairs. Did LZ see the word "auspicious sheep" printed on one side of the work, and generally the seal on this side is oval, which means "auspicious" instead of the name seal, and the ancient word "sheep" means "auspicious".

That's it. This "He Hanqing" should be the author's name. There is no doubt that the "auspicious" seal is a random seal.
