In Hulunbuir Prairie, I ate the most delicious mutton in my life. It was also a very beautiful day. In the afternoon of that day, our car arrived at our accommodation, which was a family hotel on the grassland. When I got off the car, I opened my eyes in confusion. The scene in front of me made me think I was awake and dreaming. I saw a fairy-tale courtyard appearing in front of me. The courtyard was surrounded by wooden houses, with flowers blooming in the courtyard, and Melons, yellow vegetables, green peppers, and red eggplants. Perhaps because it is located on a plateau, the flowers are particularly bright and eye-catching. They are so colorful and stunning. We will stay here that night. It doesn't make sense for someone who looks like a sweet potato to be named after a fairy. I want to see what you taste like. So I bought one to try. This taste opened my eyes again and gained my knowledge. I am even more glad that I did not miss out on another unforgettable delicacy by judging something by its appearance. The flesh of the yacon fruit is pasty in color and is as inconspicuous as the skin. But when I bite it, it is sweet and crisp, pure and free of residue, and the heart is clear and moist. After chewing it in one breath, I feel comfortable all over, and my internal organs seem to have been gently wiped. I think the so-called fairy fruit tastes nothing better than this. No wonder it dares to be called yacon, it tastes just like its name. Later, after checking the information, I learned that yacon has high nutritional and medicinal value. So when you go out, it’s right to be willing to try novel foods, and you might get unexpected rewards. I also thought that I should eat a yacon before going up the mountain. It is here to purify my body and mind. I have heavy turbidity and deep dust. How can I enter this pure spiritual place without being cleansed?
