Mount Jinfo
Jinfo Shan ("Golden Buddha Mountain", Jinfoshan, Chin Shan, Jinfushan, Chin fu shan, chin fo shan, Chinese: 金佛山), the highest peak of Dalou Mountains, located in the upper reach of the Yangtze River, is situated in Nanchuan District, the Municipality of Chongqing.
 Jinfo Shan is an isolated mountain with cliffs up to 300 m surrounding its relatively flat top.
 Its major vegetation types include subtropical broadleaf forest, coniferous forests and subalpine meadow.
 Besides typical karst topography of gorges, stone forests and cave systems, Jinfo Shan is well known for its exceptional plant diversity of 4768 seed plants. Yellow-spotted salamander
The yellow-spotted salamander ("Pseudohynobius flavomaculatus") is a species of salamander in the Hynobiidae family, endemic to China, where it is known from Nanchuan in Chongqing (formerly Sichuan), Suiyang in Guizhou, Lichuan in Hubei, and Sangzhi in Hunan Province.
 However, genetic methods have revealed cryptic species within the "Liua"–"Pseudohynobius" complex, and the actual distribution of the yellow-spotted salamander is turning out to be different.
 Only animals from Lichuan in Hubei and Sangzhi have been positively identified as being yellow-spotted salamanders, whereas animals collected from Nanchuan were described as a new species, "P. jinfo", by Wei et al. in 2009. Haiyang Nuclear Power Plant
Two units at the Haiyang Nuclear Power Plant (海阳核电站) are under construction in Haiyang, Shandong province, China.
 s of October 2016 , it was planned to go online at the end of 2016 and will be the second site to house AP1000 units, after the Sanmen Nuclear Power Station. Dalou Mountains

The Jinfo Mountain salamander ("Pseudohynobius jinfo") is a species of salamander in the Hynobiidae family endemic to China, known only from Nanchuan District in Chongqing (formerly Sichuan).
 Its type locality is a spring-fed pond on Mount Jinfo.
 "P. jinfo" specimens from Nanchuan were first assumed to be yellow-spotted salamanders ("P. flavomaculatus"), but genetic methods, and later on, discovery of adult salamanders, allowed them to be identified as a new species. Campaign to the North of Nanchuan County
