The marketing of applets is almost dead. I don't know how you can keep it up. Now all kinds of posts are saying, "You received a phone call the other day saying that we have an operation training meeting for applets, or something, so you should be careful." In fact, the marketing is not what the people on the posts said, but it is a bit spoiled by some unscrupulous developers or agents. In fact, when inviting customers, make it clear that the buying point of the applet is more of a value transmission than a flicker. Merchants do feel that the applet is beneficial to the entity business, and they will take the initiative to do it, but they cannot increase the price in disguise. Therefore, when inviting customers, it is necessary to find out what customers need at present, and what can small programs solve? This is very important. If you can't dig the pain point, the average person won't be tempted!
