Take Sanyuanqiao (Cash 7 yuan), get off and follow the direction of the car, and turn right at the second crossing. In fact, you will follow the direction of most people, because everyone will go to Shunyi Pinggu from there.
Take the 9 15 express train to the station (I remember that 4 yuan pays in cash). This bus takes the airport expressway, which is faster (Shunyi takes more than an hour if there is no special traffic jam on the Third Ring Road, of course, you can also take Line 5 from Liujiayao and then take Line 10 to Sanyuanqiao).
It is not recommended to go to Dongzhimen, because there is a queue to wait for the departure, and people are not allowed to stand outside the station. It's not slow, but Sanyuan Bridge may not have seats, but it will take more than 40 minutes to get there. You can get off at the east exit of Convenience Street.
Cathay Pacific, Xidan, Longhua and New World (said to open in mid-September) can all shop. This is a shopping center.
Convenience Street, Bolian and Feng Chun are all small commodities. These places are relatively close and can be walked. You can ask passers-by
