At present, it is a very wise choice to join the second-line underwear brand, because the second-line underwear brand has a large profit margin, the product price is not too expensive, the quality is guaranteed, and it is very popular with consumers. For example, red beans, flowers in water and farmar are all very good, among which farmar is better, the service support of the headquarters to investors is in place, the product pricing is moderate, and the performance and quality are good. As the economic level and consumption habits of different provinces, cities and regions in China are different, I suggest you make a detailed market survey of your own market first, and then choose the right brand according to your consumption ability and preferences. One more thing is very important. I must say that underwear to join is an investment, and it has the same reason as any investment. What you need to know is not how much money you can earn, but how much money you can afford to lose. As long as you have this mentality, then your mentality will not be too impatient and the success rate will be high. Wish you success!
