There are many trains from Xi'an, but the most affordable is the 2334 from Xi'an to Guiyang.

The train departs from Xi'an at 15:45, runs for 14 hours and 37 minutes, and arrives at Chongqing Caiyuanba Railway Station at 6:22 on the following day. The half price of the train ticket is 27.5 yuan, which is the cheapest, if you take the acceptance letter to buy the train ticket.

Out of the train station, turn right and walk about 200 meters, next to the Chongqing coach station, go in and buy a bus ticket to Hechuan. Highway, 27 yuan, if you don't want insurance it's 25 yuan. No one takes the 508 road at all anymore, it's the old national highway, and the cars are crappy, slow, and hot.

There should be a reception at the train station before the start of the school year, so you can inquire there, and there are also buses to and from Chongqing and Hechuan every day.

Get off at the Hechuan bus station, take a cab (3 yuan) or a rickshaw (2 yuan), and tell the driver to go to "Hailai College" (Hechuan's name for the Hechuan College of Commerce and Industry).

Newborn notes upstairs that said very well, the introduction of Hechuan is also very practical and objective.
