The central route begins with the Longquan Temple, which is a famous ancient temple in the west of Beijing where Buddhism and Taoism coexist (the Lord Wei enshrined here is as famous as the Goddess of the Miaofeng Mountain). Uphill from there, tourists can experience the ancient health preservation grounds, including the Immortal’s Cave, the Three-Buddha Cave, the Xuanyuan Cave and the Immortal’s Chair, from which they can appreciate the richness of the oriental health preservation culture and understand the determination and endurance of those who practiced asceticism in order to become immortals during the Liao and Jin Dynasties. Going further uphill, tourists can reach the Baita Reservoir, the Yinliang Pavilion where the immortals played chess, and the cliff-engraved characters “凤凰岭（Fenghuang Mountain）” which are the largest of their kind in Beijing.
