Let me answer the main point of analysis: in this way, behind Wang Laoji's "ban", there must be an invisible hand behind the scenes. This is obvious. It can be said that Wang Laoji's "advertising fee" of 100 million yuan is very valuable after combining powerful online marketing. First of all, in the sensitive period of patriotic enthusiasm, Wang Laoji established a correct and good patriotic brand image and won people's favor. Secondly, Wang Laoji used the slogan of "no sale" in online marketing, which directly boosted sales growth. At present, the communication power of online media is no less than that of traditional media, and there are more than 200 million netizens in China. It can be said that Wang Laoji used the corporate behavior of donating money to the disaster area to successfully carry out an emotional marketing. Of course, for the 1 billion yuan donated by Wang Laoji, the author has no doubt about the sincerity of enterprises to donate to the disaster area. As we all know, under the condition of fierce market competition, many enterprises often spend the money they earn on the development of enterprises, and rarely return to society and invest in public welfare activities. Many enterprises believe that social enterprises will be rewarded. But an interesting conclusion of market competition is that which enterprise can generously fund the development of social welfare undertakings in public relations, which enterprise can get enthusiastic returns from consumers. Improving visibility and establishing a good image of enterprises in the public are important conditions for the survival and development of enterprises. And purposeful and planned sponsorship activities are an effective means to communicate with the society. On the one hand, enterprises provide material guarantee for the smooth progress of social activities through sponsorship activities; On the other hand, we can show ourselves, establish a good image and create a good market environment for our own development. Wang Lao Ji Company knows the dialectics of sponsoring public welfare undertakings and donates money to earthquake-stricken areas.
