Advise on how to get to Xixi Wetlands from my hotel(Courtyard Qianjiang) using public bus or taxi.

There is no direct mode, so you are suggested to take a taxi, and the fare is about CNY55.

If wanting a cheaper way, take the subway line 4 from the Chengxing Road Station near your hotel, to Jinjiang Station. Transfer to line 1 to Fengqi Road and Exit B. Walk another 400 yards to Changshouqiao bus stop to take the bus No. 102 to West Bus Station. Walk for another 400 yards, you will reach the park.
