At present, China's joining is rather chaotic, mainly because there is no supervision, which has caused some people with no business experience to be fooled by the ability of fooling. In foreign countries, the supervision in this respect is very strict, and it is illegal for you to attract investment without a good record of many years of operation. Products with low technical content and no characteristics are not suitable for joining, because they are easy to imitate, such as slag-falling sesame cakes, and now the in-laws cakes also have this trend.
