In the northwest corner of Chinese territory, on the Qinghai-Tibet Plateau, the roof of the world, there is an ancient city with a history of more than 2 100 years-Xining. This is the cradle of the Chinese nation-the birthplace of the Yangtze River, the Yellow River and the Lancang River, the home of Wanshan ancestors, the most beautiful rainbow after the storm and the unique plateau national culture. The blue sky lures the white clouds, the grassland lures the cattle and sheep, and the mysterious western snow area lures every pious wise man; The profoundness of Tibetan culture radiates wisdom. Every creature here is so precious, so simple and full of infinite power. Butter sculpture, murals and pile embroidery, these "three artistic wonders", belong to the world cultural heritage; Sun Moon Mountain, the historical witness of the unification of Tibet and Han Dynasty and Princess Wencheng's entry into Tibet, is the watershed between China Loess Plateau and Qinghai-Tibet Plateau. Beichan Temple, the second largest hanging temple in China, and Dongguan Mosque, one of the four largest mosques in northwest China, are even more famous.
