which bus can take me from Asia international hotel to canton fair

Hi, from your hotel, you may walk to the XiaoBei Station to take the subway line 5 for 9 stops and get off at YuanCun Station, then transfer to the bus No. 44 (or No. 40 or No. 293) for 2 stops to get to the destination. If you take taxi, then the fare would be around CNY40.
