Nanjing Suijiacang Shenma?

One of the old place names in Nanjing is a compound of the names of Suiyuan and Xiaocang Mountain.

Suijiacang on the old map refers to a street starting from the intersection of Ninghai Road in the east and ending at the entrance of Hujuguan Lane in the west. It later became a fictional place name and was collectively called Guangzhou Road in the mid-1950s. Suiyuan is a private garden (i.e., Suiyuan Campus of Nanjing Normal University) that was carefully and randomly constructed on Xiaocang Mountain (i.e. Wutai Mountain) from the Ganhe River to Wulong Pond purchased by Yuan Mei, the magistrate of Jiangning County in the Qing Dynasty It was because of the government's property that Cao Xueqin had a close relationship with Yuan Mei and had the opportunity to write about the Grand View Garden with Suiyuan.

Since Nanjing Brain Hospital is located near Suijiacang, the word "Suijiacang" is used to replace "mental hospital" and "lunatic asylum" in Nanjing slang or Internet language. For example, "You came out of Suijiacang", "Did the wall of Suijiacang fall down? Otherwise, why are you here?" and other jokes. If someone mentions topics like "Suijiacang" to you, you can easily tell that he is probably from Nanjing.
