When he wants to make Cheng Ju his emperor's home, what constellation does it mean that his Ziquan Palace is occupied by clouds?

According to this poem, this should be Evonne of Song Huizong. Because cuju is good, I often take part in cuju, but I don't care about state affairs. I am a person who does nothing. Later, the capital was captured by Jin Bing, and he was imprisoned in the capital by Jin Bing. So there's what Cheng Ju writers call a smoke lock palace. According to historical records, Evonne, Song Huizong, was born on the fifth day of May in the fifth year of Yuanfeng (1082). The zodiac is a dog, and later a writ was issued prohibiting the killing of dogs in the world.

So, I guess the answer to this poem should be dog.
