I want to travel freely from Xining to Salt Lake on September 2 and 3

You can’t take a train, only a car, because the Salt Lake number from Xining to Chaka Salt Lake only runs between 628 and 828, and there are no other times. There are many shuttle buses to Haixi from Xining Bus Station. When you go to Chaka Town, Take another taxi. <br/>On the first day, Xining went to Chaka Salt Lake to play, and on the second day, took the shuttle bus to Erlangjian, visited Qinghai Lake, and then returned to Xining.
