It must be very convenient to take a bus. Come on, take the train. It's crowded, crowded and stuffy. Last time I took a bus from Yulin to Xi 'an, and had dinner in Tongchuan. When I bought the ticket, the conductor said that the bus would leave at 9: 00, 1 1: 00 and 12: 00. It took about four hours to get to Tongchuan New District, and eating was too expensive. Although it was a buffet, it took me less than five minutes to get on the bus.
