Beautiful Xiaoxing 'anling Original:

There are countless Korean pine, white birch and oak trees in Xiaoxing 'anling in the northeast ... stretching for hundreds of miles, just like a green ocean.

In spring, trees grow new branches and green leaves. The snow on the mountain melted, and the snow water merged into a stream and gurgled. The deer is walking by the stream. Some of them leaned down to drink water, others cocked their heads, admiring their own shadows in the water. This stream is full of spring water. Logs flow forward with running water, like a fleet.

In summer, trees grow luxuriantly, and dense layers of branches and leaves seal the forest tightly, blocking people's sight and covering the blue sky. In the morning, the fog rose from the valley, and the whole forest was immersed in milky fog. The sun came out, and thousands of golden rays passed through the treetops and shone on the grass in front of the workers' dormitory. There are all kinds of wild flowers in full bloom on the grass, including red, white, yellow and purple, which really looks like a beautiful big flower bed.

In autumn, the leaves of birch and oak turn yellow, and pine and cypress look greener. Autumn wind is blowing, and fallen leaves are dancing in the forest. At this time, the forest presents people with sweet and sour mountain grapes, crispy hazelnuts, fresh mushrooms and fungus, as well as valuable medicinal materials such as ginseng.

In winter, snowflakes fly in the air. The trees are covered with snow. The snow on the ground is thick, loose and soft, often reaching the knees. The northwest wind roared through the treetops, and the black bear licked his fat and thick feet with his tongue.

Xiaoxing 'anling has charming scenery all year round. This is a beautiful garden and a huge treasure house.
