I'm from Guangdong, where shoe plates or shoe factories are the ends of the earth, and the industrial prospects are not very bright, and the actual situation of a new apprentice studying at school working in a factory seems to our factory that there is no introduction. In fact, it is very simple for someone to give directions when opening the edition, and it will take a few days to a week or two. The rest is to accumulate experience at work. By the way, it is not good for some colleagues to go to other provinces. Unless you have a good relationship. Finally, you said that the running shoes version is the simplest version.
