Following the spread of the mobile internet, a large number of businesses are doing business on their mobile phones, and today those who have come to emerging markets earlier are earning a fortune. Most of the businesses that do this are based on large electrician platforms, such as skycats, poachers, corporatists, etc., and one thing that needs to be noted is that the traffic is actually on those electrician platforms, rather than on their own. Unlike the city information applet, which belongs to the business, it exists independently and has ownership once it is opened. Premiums, membership cards, christmas events. Nor does it worry about the day when all the traffic that has come to them will be lost as the platform collapses. You've got a little program on the line, and it's like you've got a whole mall system.

Many electrical platforms are generally enthusiastic about small programs because small programs are open and users will be out of the program once they have done their single consumption, to the detriment that user traffic continues to be retained by the electrician. However, the social reduction method measured at the front end of the applet opens the possibility for the next consumer to enter the program and can help the user to return to the program for consumption. Users'sharing of the social benefit can attract more users to the small program platform for consumption, and social benefit allows for a smoother process of use, such as small programs -- card bags -- purses, which can better stimulate the mobile purchasing power of a billion users。
