How to go from Shekou to Luohu. How much price ticket by train,bus or taxi ?

Take metro line 2 and transfer to line 1 at Window of the World, and get off at Luohu. It takes about 50 minutes and CNY7. If you take a taxi there, it takes about 40 minutes and CNY70-80.

Thanks a lot

Can we take a metro from Hong Kong Airport to Luohu?

No, you can’t do that exactly, since you need to pass through Futian Port. You can take Airport Express and transfer to West Rail Line at Kowloon, and then do another transfer to East Rail Line at Hung Hom. Get off at Lok Ma Chau, and then pass through the port.
After that, take metro line 4 and transfer to line 1 at Convention & Exhibition Center, get off at Luohu.

Thanks
