what is the cheapest way to get to shanghai international convention center from datong road?

You are suggested to take subway line 6 at Gangcheng Road, get off at Century Avenue Station. Then transfer to line 2 to Loushanguan Station, Exit 2. After arriving, walk southwest around 0.6 miles (1 kilometer) to get to the destination. The whole way takes around 65 mins. The ticket fare is CNY 6 per person.

Thank you very much.
