Take Incheon International Airport Line to Seoul Railway Station, 25 yuan an hour. God knows what I went through today? Looks like I'm the star of the subway ticket machine! Last time to Sydney, Australia! This time, I came to Seoul, Korea. After buying tickets, I only spit out coins. I can't get 5,000 won notes stuck. I rushed into the station in a hurry without looking at it carefully. Fortunately, I found that I didn't find enough money. I went to find the staff to open the box and withdraw money. I almost lost 30 yuan.
