During the tour, we spotted many signs reading "Danger: Mines." But Tsai could always tell which were "fake" (meaning the mines had already been cleared) and which still really had live mines and should be avoided.
採訪沿途也多次遇見「Danger Mines」（地雷危險）的警示牌，不過蔡顯國就是有辦法一眼判定哪些是「假的」（地雷已拆除），哪些才是地雷仍然深埋的危險地帶，最好不要靠近。
