I will stay shanghai lihao international hotel and i will arrive at 2pm in my hotel.

Your hotel is far from any station of the bus. My suggestion is that you walk to Chuannanfeng Highway Chuanliulu bus stop to take bus Longlin Special Line and get off at Longyang Road subway station. There you can transfer to subway line 2 to People's Square. Leave through exit 2 and walk around 5min to Urban Planning Exhibition Center. Nearby you can catch the sightseeing bus line 1. It takes around 80min for a loop route. The fare is CNY30 which can be used for unlimited rides on the bus within 24h.
