A lot of people think this map is just Taiwan rotated 90 ° counterclockwise. But in fact, if we look at the latitude-longitude grid, we can see I used a particular projection called the oblique Mercator projection, because it's the most faithful way to represent the East Asian island arcs. "
許多人以為這張圖只是把一般的台灣地圖向左旋轉 90 度，但其實看經緯線就知道，我是用了一種特殊製圖法，叫作『斜麥卡托投影法』，因為這是最能夠忠實呈現東亞島弧的方法。」
