Sorry I don’t know prices for chiles en, but any way it is very cheap,

That is not true to my knowledge. Just buy a card and put a small balance on it. The travel is VERY cheap. 50 RMB will last a ling time.

We never saw a credit card payment as an option. Strictly cash.

Private cars are a total rip off. 1. Take subway to Dongzhingmen - 4 RMB 2. Take bus 916 Express - stop at Bedaijie (15th stop) - 6RMB 3. Once you go down, ignore all the black taxis (they will pester you) and just in front there a official taxi stop (blue & white). Taxi to Mutianyu entrance (42 RMB). To come back, once again they will pester you with private cars. You have a bus going straight to Qianmao for 30 RMB per person. If you visit Mutianyu, slide down the toboggan. I found it super cool.

1.the Airport high speed line or Airport light rail is called ji chang qing gui (in pin yin). The Metro card for all the public transportation including both subway and bus called gong jiao yi ka tong(in pin yin) can be purchased at the Airport Terminal 2 and Terminal 3 arrival areas, the Airport high speed line is RMB25 which is much higher than the regular Metro lines. The airport high speed line will bring you to the Metro regular lines, RMB4-6yuan each regular subway line depending on how many stops to your destination. The regular Metro card vendor machines accept 1yuan coins and paper money 5 and 10 yuan; 24-1yuan coins should be fine at the machines for each purchase. 2.If you try to pay for the Metro card and top it up with a lot of 1yuan coins, better not to use the machines but go to cashiers; not sure how many 1yuan coins could be accepted, 50-1yuan coins for a Metro card shouldn’t be a big problem, there is no law against it, it just takes time to count and not easy to carry around. 3.To spend 1080-1yuan coins; suggest to go to nearby bank to exchange most of them to paper money 5 or 10yuans; spend the rest of coins for the local delicious snacks and souvenirs and Richshaw ets. Happy travel!

it's absolutely ok for traveling with subway.There is English in subway,just make sure you know the direction which station you need to stop.If you don't know you could always ask the people,the people in subway station is very helpful.They speak English.

En máquinas y se pueden comprar en cualquier estación. Las máquinas funcionan en chino e inglés. Es muy sencillo.

Nosotros usamos viajes individuales, no creo que compense comprar ningún bono.

If I remember correctly, there are Beijing subway system has seven lines and all are operational. The lines are color coded and easy to navigate.
