How to go from Shenzhen North Station to Hong Kong Nathan Road and from HKIA to Guangzhou ?

Just in the North Railway Station, there are direct buses going to HK. You can take one and get off at Mong Kok or Prince Edward Station, which are just located on Nanthan Road. The fare is CNY80.

In HKIA, there are also direct buses going to different areas of Guangzhou, you can take one and drop off at the nearest stop to your destination.

Thanks a lot Heidi !
