Chuang Chi-fa, a researcher at the National Palace Museum, believes that this was one of China's earliest maps of Taiwan. "It was probably used by the Qing court to attack the pro-Ming forces of Zheng Chenggong (Koxinga)," says Tsao Yung-ho, a professor of history at National Taiwan University.
故宮博物院研究員莊吉發認為，這是中國人最早的手繪地圖之一；台大歷史系教授曹永和認為，「應該就是清軍攻明鄭的軍用地圖」。
