How to reverse from Shunyi Fengbo to Zhongguancun?

Take 915 or 918 to Sanyuan Bridge, then walk back about 500 meters, go to the opposite side and take 302 and get off at Hailong. Or take Metro Line 10, but you need to walk for a long time to get to the subway station. The advantage of the subway is that it is fast. You save money by taking the bus, although it is only a few cents, but in fact, when you add it all up, the time taken by taking the subway and taking the bus is almost the same. When buying parallel imports, it is best to bring someone knowledgeable, otherwise it will be too easy to buy fake ones, or do some research online.
