Reason for recommendation: The doll food is clean and the fans are smooth. It's good for the guests. The lack of potassium is also an important reason why many people find themselves in a state of mental insomnia, over and above the lateness of the night and the irregular diet. The pharmacological value of doll food is also high, which is considered by Chinese doctors to be mildly cold and often consumed with the effect of acupuncture, dysentery, urination and thermal detoxification. A fan is a common diet on the table. The best fans are green beans, which can also be made of corn starch or melon starch, but of less quality than green bean fans, with the largest number of straight-chain starch in green beans, which are not easily fertilized when cooked, and the least glitter. The nutrients of fans are mainly minerals such as carbohydrates, dietary fibres, proteins, sootic acid and calcium, magnesium, iron, potassium, phosphorus and sodium。
