I went to Haixinsha from Shamian yesterday.
When you get out of Haixinsha, you can walk behind the decoration of several large kapok flowers in Huachang Square. You can take APM line (all-way 2 yuan) and get off at Linhe West Station, then take Line 3 and get off at Sports West Station, then take Line 1 and get off at Huangsha Station, then exit D, walk left on the overpass, and walk there to Shamian Island. (If you think this is inconvenient, you can check it on "Guangzhou Bus Network". )
