The glass business is simple, and it is quite complicated to say that it is complicated. I have processed 8 million business orders in April. Facade business is the best. What is difficult to run is the business on the construction site. Now this information age does not depend on price. It depends on the quality and service. It depends on patience. Specific speed. What matters is how you impress your customers. The most important thing is that you should know your own company, delivery, workmanship, quality and company management, all of which you should know clearly. Only in this way can we have the confidence to handle bigger business.
