1 1 Depart from Zhengzhou to Dunhuang, Zhangye, Xining and Qinghai Lake. It takes 8 days to find the best route, accommodation and scenic spots. Thank you!

Day 1: Mingsha Mountain, Crescent Spring, Mogao Grottoes: Dunhuang

After picking up the bus, visit Dunhuang Mogao Grottoes, which is known as the treasure house of Buddhist art in the world. It is 30 kilometers away from Dunhuang Grottoes and takes 40 minutes. It is a treasure house of culture and art integrating architecture, painted sculptures and murals, and has precious historical, artistic and scientific values. It is a historical treasure of the Chinese nation and an excellent cultural heritage of mankind. 1987 is listed in the World Cultural Heritage List by UNESCO. In the afternoon, I visited the magical desert wonders Mingsha Mountain and Crescent Spring, which became the wonders of the Millennium sand spring because "the ancient sand does not fill the spring, and the spring does not dry up". Visitors can climb mountains barefoot, slide sand and climb sand dunes by camel. Dunhuang is 5 kilometers away from Crescent Spring. Visit Shazhou Night Market in the evening, and then stay in the hotel to rest. Interested friends can go to the Dunhuang Grand Theatre to see the Dunhuang Goddess, and then stay in a hotel.

Day 2: Ancient City-Yumenguan-Han Great Wall-Yangguan-Ya Dan Landform Other Western Hotels: Dunhuang.

After breakfast, take a bus to Dunhuang ancient city to watch the sunrise, and then go to Yumenguan, which is known as the "Millennium Ancient Pass". It is an important military pass in the Han Dynasty and an important pass on the defense line of the Great Wall in Hexi. 1998, Yumenguan and Han Great Wall were listed as national cultural relics protection units. An ancient poet once chanted, "Why should Qiangdi complain about Liu? After that, I visited the most intact ancient Great Wall of Han Dynasty, and visited the first batch of national geological parks of Ya Dan landforms called ghost towns by local people. Ya Dan landform is called the Museum of Natural Sculpture, and it is found in many famous buildings in the world, such as Tiantan in Beijing, Potala Palace in Tibet, Golden Pagoda in Egypt, the Sphinx, Mongolian yurts on the grassland and so on.

Day 3: Dunhuang-Jiayuguan-Ejina: Ejina

After breakfast, take a bus to Jiayuguan and visit Jiayuguan Great Wall, the first male pass in the world. -Located in the middle of Hexi Corridor, it is the key pass at the western end of the Great Wall in Wan Li in Ming Dynasty. As the saying goes, the Great Wall of Wan Li starts from Shanhaiguan in the east, reaches Jiayuguan in the west, and climbs the tower overlooking the desolate Gobi Desert and the majestic Qilian Mountains. After the visit, go to Ejina.

Day 4: Juyanhai-Shenshu-Zeke Port-Heishui City-Guailin-Datong City-Hongchengsu: Zhangye

Take the early bus to visit the final destination of weak water and quicksand. Juyanhai felt the preciousness of water and the miracle of life here. Then take a bus to the sacred tree known as "King Populus euphratica". This is a holy place for priests to recite scriptures and pray for good weather and prosperity of grass and livestock. After that, I went to Ceke Port to enjoy the exotic customs of China and Mongolia separated by a water. After exploring the most intact site of Xixia ancient city on the ancient Silk Road by car, Heishui City can pick up various Xixia tiles and white cattle bones from time to time. The black city surrounded by quicksand may disappear in the long river of history in another 20 years. After that, I went to Datong to see the ruins of the ancient city, recalled heroic anecdotes, and imagined the grandeur of the desert "the long river sets the yen". After that, I visited the Red City, a cultural site of the Sui and Tang Dynasties-I continued to visit the strange forest known as "Living for a thousand years, not falling down after death, but being immortal for a thousand years"-and walked into the scenic spot, all kinds of Populus euphratica were vividly displayed in front of me, some pierced the blue sky, some curved around, and some collapsed, with different shapes and various shapes. Then return to Zhangye to stay in the hotel or watch the sunset in Danxia landform. (Zhangye City, located in the middle of Hexi Corridor in Gansu Province, was one of the four counties in Hexi in ancient times, which means "breaking Xiongnu's right arm and opening China's armpit". Zhangye Danxia landform is located in the hilly area of Fiona Fang 100 square meter, with unique shape and colorful Danxia landform. Danxia refers to isolated peaks and steep rocks formed by long-term weathering and stripping of red gravel and flowing water erosion. Because Ejina Zhangye is far away, Ejina scenic spots can be visited selectively, so the sunset of Danxia in Zhangye is arranged according to time.

Day 5: Big Buddha Temple and Qinghai Lake Accommodation: Qinghai Lake

Take a bus to Zhangye and visit Zhangye (Big Buddha Temple) early. The temple was built in the first year of Yong 'an in Xixia (1600). In history, the masters of Xixia first excavated a reclining Buddha covered with blue tiles and built the Great Buddha Temple. There are three existing buildings: the Great Buddha Hall, the Sutra Pavilion and the Earth Pagoda. The Great Buddha Hall is meters high, with a wide area and a large scale. There is a 6-square-meter brick sculpture on both sides of the temple gate, with "Climbing to the Blessed" and "Western Holy Land" on the left, and "August 3rd Mo Chi" and "Yuan Di Performance" on the right. Then go to Qinghai Lake to watch the sunset for kilometers.

Day 6: Qinghai Lake-Xining Hotel: Xining

Take the early bus to Qinghai Lake and visit the largest inland saltwater lake in China. Qinghai Lake is rated as one of the most beautiful lakes in China. Visit Tibetan tribes and folk museums in the scenic area. At the same time, tourists can experience the feeling of taking a boat at a height of meters in Qinghai Lake, watch the China torpedo launching test site on Qinghai Lake at close range and enjoy the beautiful scenery of Qinghai Lake. Qinghai Lake is the best place for tourists to camp. At that time, the temperature was only around and the climate was cool and pleasant, so they stayed in Qinghai Lake.

Day 7: Qinghai Lake-Xining, Accommodation: Xining

Take the early bus to Ta 'er Temple in Xining, and you can visit Daotang River (Sun Moon Mountain) along the way. It is located in the southwest of Huangyuan County, Qinghai Province, to the east of Qinghai Lake, with the highest elevation of meters. The origin of the name Sun Moon Mountain is related to Princess Wencheng. Legend has it that Princess Wencheng was heartbroken when she went to He Fan. The King of Tang gave her a precious mirror to comfort her and asked her to go to the border between China and Tibet. When she takes it out, she can see her hometown and her relatives. After all the hardships, the princess went to Chiling. When she looked in the mirror, she only saw her thin face and Chiling Mountain in the sunset. At this time, she realized that her parents had deceived herself for the country. In grief, she threw the mirror out and broke it in half, just landing on the hill. According to the rising moonlight, the east half faces west, reflecting the afterglow of the sunset, and the west half faces east.
