On this day, 39 years ago, on October 6, 1986 (September 3, 1986 in the lunar calendar), my country's Arctic village Mohe was first navigable by helicopter. On October 6, 1986, a motor roared above Mohe, my country's Arctic village. At about four o'clock in the afternoon, a silver eagle accurately landed at a border company's residence near the statue of the "Northern Border Sentinel". This is the first test stop of a helicopter sent by the Shenyang Military Region in the northeastern border area. This was the first time the local people saw the plane and ran around to inform each other. The border guards said with emotion that ten years ago, we bid farewell to horse-drawn sledges and replaced them with car wheels. Today, we put on wings again.
