The folk song "Three mountains are present, three mountains are hidden and three mountains are not seen" has been circulating in Fuzhou for a long time. Among them, "three mountains are now" refers to Pingshan, Yushan and Wushan. These three mountains stand on the central axis of Bayi Road today, which is very eye-catching, so it is called "now". However, there is no conclusion between "three mountains are hidden" and "three mountains are invisible", and there are generally two statements. One is based on the Archaeology of Rongcheng by Lin Feng in Qing Dynasty: Luoshan, Shan Zhi and Dingwushan are "three mountains"; Lingshan, Zhongshan and Yuchi Mountain are "invisible"; Secondly, according to the Ming Dynasty's Min Shu, Luoshan, Yeshan and Yuchi Mountain are "hidden three mountains" and Longshan, Zhongshan are "hidden". No matter what kind, the hidden three mountains are all branches of the "three mountains now" (Pingshan, Yushan and Wushan), and some are like hillsides. With the widening of roads and the density of civil buildings in past dynasties, these hills were either leveled or blocked, so that they became "hidden" and "invisible". Now introduce their website as follows:

Luoshan, a hill behind Nanmen Union Medical College Hospital.

Yeshan, a hill behind the Provincial Health Department of Gu Ping Road.

Yuchishan, also known as Minshan, is located in the wall of Guanglufang Provincial High Court.

Longshan, also known as Lingshan, is located in Seven Stars Well Lane of Gulou today.
