Anhua County, Hunan Province, Ning Zhuangzhi In 1983, the loach was raised in a paddy field with 4 points of “late rice seedling and late rice”. One year’s feeding time was 1,500 kg of loach and 350 kg of rice, equivalent to 3,750 kg of mule loach and 875 kg of rice. His main experience is: First, to create conditions for the production of loach 4 minutes to support paddy fields, one side of the mountain, on three sides connected with the paddy fields, leeward sunny, convenient irrigation and drainage. In order to prevent the loach from escaping, before the planting, the paddies around the paddies will be strengthened and the paddy fields shall be protected by triadimetry. A ditch shall be opened along the sides of the paddock. Each paddy will be opened with a 5-meter- 1.5 feet ditch width, see hard bottom,
