| Do you want to go to Beijing? Let me introduce the ways from Shanghai. The train fare (价格) is 230 yuan, the bus fare is about 300 yuan, the taxi fare is about 580 yuan, and the plane fare is about 2,240 yuan. You see, the cheapest (最便宜的) way is by train. But it takes the most time. It takes you two days to get to Beijing. But taking a plane is about three hours' flight. It's about eight hours' drive by taxi and you need one day by bus. | ||||||
