1, first of all, choose a reliable company, so as to ensure success;
2. Secondly, it depends on whether the cost performance of the company's products is in line with the mass consumer groups;
3. Then, look at the profit rate of the product and see if you can make money;
4. Thirdly, it depends on whether the company's joining support is strong enough for you to have no worries;
