New Zealand's famous gold mining area in South Island has also led to the prosperity of Queen Town. The dream of Gold Rush has attracted a large number of Chinese. The Arrow River is the gold rush center. Later, the gold mine has been exhausted gradually, but the ecological damage on both sides of the river is serious. After vigorous protection and restoration of vegetation, the ecological restoration on both sides of the Arrow River has now opened up pedestrian trails and public parks. Occasionally, there are people looking for gold in rivers and sands, just to kill time.
