So, theoretically speaking, although there are many small mountains within the Qin Island City area, totaling several dozens, most of them belong to the Lao Mountain Range, like Beiling Mountain where Zhang Yanhang just went, which is a typical subsidiary ridge developed from the southwest branch of the Lao Mountain Range.
Even as a subsidiary ridge of the Lao Mountain Range, Beiling Mountain not only inherited the mountain springs from the Lao Mountain Range but also developed a small lake within it. Zhang Yanhang often went there to drink springwater when he was young, and he had to admit, it indeed tasted completely different from the chlorinated tap water.
Regarding the subsidiary ridges of the Lao Mountain Range, Zhan Mountain Temple, which was mentioned earlier among the local sects of Qingdao City, was established relying on one of these ridgelines—"Zhan Mountain"—from the southwest branch.
