In fact, it's not much money to take a taxi from Shenyang Railway Station to the South Yard. You can take the subway and sit in the middle street. Under the entrance of Dunan New Town in the business district, go straight at the first crossing diagonally across the street, and then take 13 1, 1 13 to the south yard. When you get there, you can look at the bus stop.
You can take bus 123 to Shenyang University, but this is the north campus. Ask any student in a school and take the underground passage to the south campus.
You can pay cash in the canteen.
