First of all, understand the equipment and foundation of your industry. Salespeople rely on customers, and scattered customers have big profits, but they are generally a one-time deal. It's best to make some leaflets and go to wedding companies, advertising companies and media companies. As long as the quality is guaranteed and the price is not too high, you will use yours slowly. If the service is good in the future, you will be a frequent visitor. This will be long-term. Good luck!
