The venue of the symposium is meeting rooms 2 (plenary session and parallel session A) and 8 (parallel session B) of the Convention center of Beihang University. It is located in the building block of "New Main Building" close to the east entrance of Beihang University. Here is the map of Beihang University, where you can find the symposium venue, Vision hotel, the training center of Beihang University, and the Main Building (where most faculty of school of physics work).
If you arrive at Beijing by plane, the easiest way to reach Beihang University is by taking a taxi. The distance from Bejing airport to Beihang University is about 30 kilometers and it costs about 100 Chinese yuan. Please show the follow Chinese sentence to the taxi driver: [请带我去北航唯实宾馆,海淀区学院路39号] if you stay at Vision hotel. If you stay at the training center, show the following instead [请带我去北航培训中心,海淀区学院路37号].
One can also take a shuttle bus (No. 5) and get off at "Xueyuanqiao" [学院桥], the second to last station of the line, which costs only 16 Yuan. "Xueyuanqiao" station is close to the north entrance of Beihang University. Unfortunately, it is on the other side of the street. From the station, one should first cross the street using an overhead bridge and then enter the university from the north gate. Following the route shown on this map, it is not difficult to find both Vision hotel and the training center, which takes 15-20 minutes depending on how fast one walks. More information about Beijing airport shuttle is here.
A third alternative is taking the subway. You can take subway at both Terminal 3 and Terminal 2, then switch to line 10 at "Sanyuanqiao"[三元桥] in the direction of "Bagou"[巴沟]. Whether you will stay at Vision hotel or the trainning center, you should get off at "Xitucheng"[西土城], and then follow the route on this map.
