can you guide me to reach mutianyu section from guangzhou? like bus number ect...

Adzim, the wall is located in the suburbs of Beijing, which is far from Guangzhou. You need to take flight or train to Beijing first. High speed train is recommended. The second class seat costs CNY862. It takes around 9 to 10 hours. If you can find discount air tickets, you may fly to Beijing.

By train, you will arrive at Beijing West. You may take no.83 bus from the railway station to reach Changchunjielukoudong. There you can change subway line 2 to reach Dongzhimen. From there, you can take 916 express bus to Huairou North Street. Then you may take a taxi to reach the wall.

By plane, you can take airport express to reach Dongzhimen. Then use the above route to visit the wall.
