I have to say that most of the production process of spicy noodles are very unhygienic, for example, 315 evening party also exposed a lot. But there are also very formal chili strip production company's, such as Weilong (non-advertising), after all, do so big, look at the packaging and so on are very clean. But if you like to eat spicy noodles, it is recommended that you can try to make your own Oh ~ there are also many production tutorials online.
