Qisongchi, looking around at the pavilions of precious trees, is as desolate as the forest and the sea, and goes down to Yuntai, exploring the heavy springs, connecting the sky from top to bottom, painting green in spring, shading in summer, dyeing golden red in autumn, wearing silver armor in winter, and changing clothes all year round. Although it has gone through many vicissitudes, it is still flourishing, and tourists claim to be tutting.

The ancient forest in Tansong village is now divided into two parts: the forest at the entrance of the village and the forest behind the village, also known as the lower forest and the upper forest. Among them, the village forest is the main mountain, and the main mountain range of the village forest is called Tiger Mountain. Tan Songren believes that Feng Shui forest plays the role of "hiding wind to get water" and protecting "life", so it is forbidden to cut down and destroy it. Fengshui Forest has been managed by Dai Ancestral Hall. Notice is issued every year, and it is forbidden to bring knives and axes into the forest. Dead wood firewood in the forest is only allowed to be picked up by lonely old people with bare hands, and offenders are punished according to clan rules.

Fragrant fruit trees have the ability of "sprouting roots and tillering", and the phenomenon of "single tree forming a forest" often appears. At the distance of10m, there are two fragrant fruit trees with roots and tillers, both of which are18m in height and 20cm in DBH. In addition, there is a big beech tree and a Betula luminifera. The former is nearly 30 meters high, the trunk is smooth, round and full, with the same thickness from top to bottom, and the age of the tree is over 100 years. The latter tree is 25 meters high and has a bust of 2 meters. It grows on the edge of the forest, with lush foliage and heroic spirit. There is also an old Ailanthus altissima with a height of 3 1m, a bust 1.8m, a branch height 16m and a crown width 10× 10m.

Its trunk needs many people to hug, its four seasons are evergreen, and its crown stands like a huge green umbrella in the ancient forest.

It is recognized as an endangered natural rare anticancer plant in the world and an ancient tree species left over from Quaternary glaciers. It has a history of 2.5 million years on earth. Due to the slow growth rate and poor regeneration ability of Taxus chinensis under natural conditions, a large-scale raw material forest base of Taxus chinensis has not been formed in the world for a long time.
