Wakan soup contains a lot of monosodium glutamate (MSG), should be higher than the standard dosage of more than one or two times, first of all, because the soup is surprisingly fresh, even if the level of cooking is not possible, only a large number of MSG; secondly, I drank a few times, every time I drank it, the mouth will peel off, the tongue will be numbness of the palate, and always thirsty, and it will last for two or three days. All of these manifestations are signs of a serious overdose of MSG. If you want to live a few more years, it is better to drink less.
