From the small cottage of the forest ranger comes the sound of joyous singing and dancing. Weekend visitors are enjoying the most memorable and grand spectacle in their lives
One of the distinctive biological characters of the lake is a small wooded island in the center of the lake and some boats can ferry tourists there, and on the island grow dense spruce, abies-fabri and azalea woods. All of the green grasses, zigzags, singing birds and fragrant flowers make you feel that you are in a fairy world. Right around the lake there is a dense azalea forest, whose flowers are often in full bloom. In the fifth month of the Chinese lunar year tourists can see a peculiar sight-the fallen azalea flowers afloat on the water, while the fish amuse themselves in the shallow water of the lake, swallowing the fallen azalea flowers. The fallen flowers are little poisonous, and will cause them to appear "drunk" as they float on the surface of the lake, so it is called " Fish Drunk by Azalea.
In later spring and early summer，wild flowers bloom profusely in the meadows, the glorious colors shine like twinkle stars in a sky of fresh green grass; In the depth of winter, flocks of cows, horses and sheep sport in the meadows, immersing in joy. The Bitahai Lake is encircled by virgin forests. Black bears, brown bears, monkeys, parrots and lynxes, clouded leopards, buffaloes, squirrels also can be found in the forest.
