Tangshan Yutian worked to establish a national cultural tourism consumption pilot city, and the mountain spring moistened rouge rice. Longquan Cave, one of the eight classic scenic spots in Yutian, is located in Koizumi Village, yutian county.
Spring water belongs to the hot spring series, which remains unchanged all year round. Due to seasonal factors, people feel warm in winter and cool in summer. In the cold winter, hot springs rush and white fog pervades, covering the surrounding trees with plain clothes. In cool summer, spring water irrigates the rice fields in front of the mountain, which is lush and green, replicating the pastoral scenery under the chrysanthemum fence. In autumn, this rice named Yutian Rouge comes from a golden land, which is a treasure in rice and is used as a tribute to the palace.
