Many years of specialized map study have accustomed Wei Te-wen to seeing, through pictorial images, how outsiders understood Taiwan. He is even in possession of a situation map of Taiwan published by the Chinese People's Liberation Army in 1962 with information on troop stationing, harbors and oil depots from south to north, witness to the high level of cross-strait tension existing at the time.
多年專研地圖，讓魏德文習慣從圖像資訊來觀看外人如何理解台灣，他手上甚至有一張大陸解放軍於 1962 年印製的台灣形勢圖，圖上標明台灣由南而北各地駐軍、港口、油田等資訊，可以印證當時兩岸箭拔弩張的氣氛。
