Tianmu Mountains
天目山
Giant cryptomerias, wild ginkgo and the mountain that named tenmoku
The Tianmu Mountains, the “Eyes of Heaven”, rise to about 1,500 metres in Lin'an, north-western Hangzhou, where West Tianmu is protected as a national nature reserve and a UNESCO biosphere reserve. The mountain is known for its ancient forest of giant cryptomerias, for a population of ginkgo long thought to be among the last wild ones, and for the Chan monasteries whose tea bowls gave the Japanese word tenmoku.

Key facts
Overview
Tianmu has two summits, East and West Tianmu, each with a small pond near the top — the two “eyes” of the name. West Tianmu, the higher, carries the nature reserve: a steep, stepped slope of forest from subtropical evergreen woods at the foot through mixed deciduous forest to dwarf woodland on the summit ridge.
For botanists it is one of the classic collecting grounds of eastern China, with a long list of species first described here. For Buddhism it is the mountain of Gaofeng Yuanmiao and Zhongfeng Mingben, Yuan-dynasty Chan masters whose monastery drew students from Japan; the dark-glazed tea bowls those students took home were called tenmoku, the Japanese reading of Tianmu.
How the landscape formed
The Tianmu range forms the watershed between the Taihu basin to the north and the Qiantang River to the south. Its core is Mesozoic volcanic rock — rhyolite and tuff — with granite intrusions, lifted into steep ridges and cut by deep valleys. Weathered cliffs, rock towers and waterfalls mark the upper slopes. The mountain's position near the coast and its height give it high rainfall and frequent fog, which sustain the dense, moss-hung forest.
Highlights

Plants and wildlife
The reserve is small but exceptionally rich, with more than 2,000 species of higher plants recorded and dozens of species named after the mountain. Its old-growth cryptomeria stand, with hundreds of trees of great girth, has been protected by the monasteries for centuries.

Culture and legend
Buddhist and Daoist hermits used the mountain from early times, and Prince Zhaoming of the Liang dynasty, compiler of the Wen Xuan anthology, is linked by legend with East Tianmu. Its great age was the Yuan dynasty, when Gaofeng Yuanmiao and his disciple Zhongfeng Mingben made West Tianmu a centre of Linji Chan. Japanese monks who studied there carried back its teachings and its tea culture.
