Take bus Jia定 12 to Bolesquare Station, then walk 330 meters to reach Fuhuata Tower.
(Note: "Jia定" is phonetically translated as "Jiading" in pinyin, but the correct and established name for this bus route is "Jia定 12." However, for English speaking audiences, it is typically written as "Jiading 12.")
