On August 8, we and Yu Xinxujing couple began the first day of a new self-driving journey. It rained in the morning and the temperature dropped to 8 degrees. We set off at 8 o'clock and took Ninggui Expressway to Ta'er Temple. Ta'er Temple is a holy place for Tibetan Buddhism and a must-visit attraction for famous tourists in Xining. Despite the rain, there were many people. We went in and turned around, chose the Great Jingtang to visit, murals, Buddha statues, scriptures, prayer wheels... We do not understand Tibetan Buddhism, but with compassion and fear and piety, we closed our eyes and worshiped three times. Leaving the Ta'er Temple, take the S101 Provincial Road, the West Inverted Highway, and the G109 National Road. After the Sun Moon Mountain, the Inverted River and Qinghai Lake, go to Heimahe Township. At this time, the rain stopped, and this road was driven on the Qinghai-Tibet Plateau above 3,000 meters above sea level, with beautiful scenery along the way. From ancient times to the present, along the Qinghai-Tibet line into Tibet, Sun Moon Mountain and the Daoqi River are important stations that must pass. The Daoqi River starts from the east and enters Qinghai Lake from the west, and runs more than 40 kilometers. It is the only river that flows quietly westward. Legend has it that Princess Wencheng married Tubu Songzan Ganbu far away, on the way to Tibet, when he arrived at the Sun and Moon Mountain, he looked back at Chang'an, looking at a desolate place to the west, thinking of his hometown parents, sad, tears westward, tears into this inverted river. Because of the sad legend, the tears of Princess Wencheng of the Falling River 111. We not only admire the scenery along the way, but also enter the Sun Moon Mountain, Falling River, Qinghai Lake Erlangjian Scenic Area to visit. At 7 pm, arrive at the harbor homestay in Heimahe Township by Qinghai Lake ⋯⋯ It is 259 kilometers today.
