Super busy airport in the Chinese capital. The airport is very fast pace. There's a metro line that connects passengers from terminal to terminal. However, I don't find the workers there very helpful, especially if you do not speak the language. Make sure to do research before hand and to know where to go to save time. On the bright side, airport is not that far from the city center, saving me a lot of money.
