The main reason for the graininess, soft gluten, taste and texture of Yuanyang rice is that the original yang rice is planted on the land after the improvement of the Yellow River water, and it is rich in organic compounds and various trace elements. The watering of the Yellow River water, combined with the special climate of the area with large temperature difference between day and night, has created the first-class quality of the original Yang rice. Interestingly, the county's saline-alkali land has given the rice an innate alkalinity, so that the original yang rice is full of flavor without cooking with alkali.
