Rice noodles, also known as rice noodles, refer to strip-shaped and filiform rice products made from rice by soaking, cooking, layering and other processes, rather than powdered substances made from rice by grinding.

Vermicelli is one of the common foods in China, and is often called vermicelli and winter noodles (mainly in Taiwan Province Province), spring rain in Japan, noodle soup in the Korean Peninsula and noodles in Vietnam. The best vermicelli is made of mung bean, corn starch or sweet potato starch, but the quality is not as good as mung bean vermicelli, because mung bean has the most amylose, which is not easy to rot when cooked and tastes the most greasy. Similar to spaghetti, it is sold after drying, and it is best to soak it in water to soften it before eating.

The production method is also different.
