Dinggong Village is about two kilometers from Yuancheng proper. In the past, each time it rained or snowed the road would turn into a quagmire. When the leaders of the township saw the students trudging back and forth, they invested RMB 100,000 to build an asphalt road running out to the hamlet. This was the first ever such transit way for the village, and the locals call it "Archaeology Road."
丁公村離苑城鄉約兩公里，每逢下雨或下雪，道路泥濘難行，鄉領導看到師生們來回奔波，於是投資十萬元，特別為師生們修一條通往丁公的瀝青路，這是鄉裡第一條柏油路，鄉民們稱為「考古路」。
