Butterhouse has three meanings: 1. Refers to a brothel. 2. Refers to the women in the brothel, mostly prostitutes. 3. Xingguang Tower, which was built by Emperor Wu of the Qi Dynasty, later also generally refers to the residence of the emperor.
"Butterhouse" has been called a brothel for many generations since the Tang and Song Dynasties. In fact, this is a misinformation. "Butterhouse" first referred to the residence of the emperor. Yuan Mei of the Qing Dynasty said in "Suiyuan Shihua": "Emperor Wu of Qi painted green paint on the Xingguang Tower and called it a brothel." He also pointed out: "Today, it is wrong to call a brothel a brothel." It can be seen that the "brothel" was originally the residence of the emperor. Therefore, Cao Zhi during the Three Kingdoms period The poem goes: "The brothel is close to the road, and the high gate is surrounded by many gates."
The earliest call for a brothel to be a brothel comes from the poem "The Mulberry Pickers in Wanshan" written by Liu Miao of Nanliang Dynasty, which contains the line "The prostitutes are so sad that they end up going to the brothel." The word "brothel" in the sentence is borrowed from the previous one. People misrepresented it. Later, literati and poets spread the rumor and called the brothel "brothel".
