Stephy: To pass these red shark fin-looking barriers, you’ll going to have to buy a subway ticket. Subway fare is relatively cheap compared to taxi fare. Taxis can range from 10 to 100 yuan depending on distance. Whereas a one-way subway ticket to any destination costs a flat 2 yuan, or 30 cents in the United States. Let’s go and get a ticket.

If you have a 5 or 10 yuan bill on you, you can use one of these ticket machines. Directions are also available in English. Otherwise, head over to the ticket counter.

Stephy: 谢谢。(Xièxiè.)

Stephy: Remember we need to first travel to the Xidan stop for a transfer. So, let me ask which train to take.
