Any industry is profitable and not profitable. Think about why you want to do this business, what is your business model, whether you are a brand, a store or a channel, whether the sales method is a combination of online and offline, if not, is the sales model easy to be replaced? Does the product have an absolute advantage? Reflect on yourself more. If you don't do well, change careers, but the premise of changing careers is that you have to understand an industry. It is empty to change careers blindly. If you don't make money, you must first reflect on your business model.
