We passed the "upside-down river" Why is it called the upside-down river? Because other rivers flow from west to east, but the upside-down river flows from east to west, so it is called the upside-down river. On the way, we passed by golden rapeseed blossoms. My eyes were filled with blue. Finally, I saw the beautiful Qinghai Lake in my dream. Under the sunshine, the lake sparkled like a huge rubbed blue satin. Mother said - "Qinghai Lake is a sapphire embedded in the grassland. " I said - "Qinghai Lake is a pearl on the grassland. " By the lake, there are a few children riding leisurely. Master Li, a chartered coach, tells us many beautiful and moving legends about Qinghai Lake. He is very good at taking care of people's beautiful scenery and laughing all the way. It's right to find Master Li when traveling to Qinghai Lake. I left Master Li's telephone and micro-signal here at 13897672884.
