For instance, the military plans to open the Mashan observation post, the one nearest to the mainland, so that visitors won't need to apply for permission first. The longest tunnel in Asia, which has a military use, has also long been partially open to visitors.
譬如軍方計畫開放離大陸最近的馬山觀測站，參觀者不須再事先申請；具軍事用途、全亞洲最長的中央地下坑道也早就選擇性的開放參觀。
