Three mountains refer to the legendary three fairy mountains on the sea, namely Penglai, Yingzhou and Abbot. Later, these three mountains expanded into three famous mountains in China, namely Huangshan Mountain in Anhui, Lushan Mountain in Jiangxi and Emei Mountain in Sichuan. There are other sayings about the three famous mountains, such as replacing Emei Mountain with Wuyi Mountain or Yandang Mountain. The five mountains are Mount Taishan in Shandong, Huashan in Shaanxi, Hengshan in Hunan, Hengshan in Shaanxi and Songshan in Henan: Mount Taishan in Dongyue sits on Mount Huashan in Xiyue, Mount Hengshan in Nanyue flies to Mount Hengshan in Beiyue, and Mount Songshan in Zhongyue lies down.
