It is worth mentioning that the tower's flagpole, which has been jokingly called "The Greatest Pole Under Heaven," is made up of five large, medium and small cannon barrels joined together. A few years ago when the flagpole had to be replaced because of rust, the president's office specially commissioned a fengshui master to calculate an auspicious day for raising the new pole.
值得一提的是被戲稱為「天下第一桿」的塔上旗桿，是由五節大中小砲管接起來的，幾年前因旗桿生鏽了要換新，總統府還特別請風水師算好吉時才立桿。
