Modern buildings on the Bund lined up along the west bank of Huangpu. Although they have their own characteristics, due to the similar style, it is not easy for non-professional ordinary tourists to get on the top. However, Shanghai Customs Building, but there is a very obvious mark - the clock tower, it covers a small area, but the height of 11 floors in many buildings stand out, especially at night, it is really eye-catching. The building was the headquarters of the "People's Security Team" before liberation, and the exterior wall has cultural relics nameplates and commemorative reliefs, but it is currently not open to visitors from the office. Because the top bell tower is closed step by step, it is not visible on the sidewalk in front of the building, and the best viewing angle is in several high-rise buildings on the Huangpu River or Pudong.
