At present, most Chongqing noodle training courses are basically in the thousands, more than 5,000, more than 4,000, more than 3,000 and more than 2,000. See if you can accept that price yourself. Of course, hot noodle restaurants cost more than 10 thousand, which is also very common, but you may not be able to learn the real recipe.
It is recommended to come to a special catering training school and learn all the recipes for a fee.
