Legal analysis: marketing in the name of public welfare is generally not illegal. Public welfare marketing refers to combining product sales with social problems or public welfare undertakings and making donations for related public welfare undertakings. Public welfare marketing can not only increase the funds for charitable activities, but also expand the visibility of public welfare projects and further develop charity. A good public welfare marketing can achieve a win-win situation, and it is also a very representative model of the combination of business and public welfare.

Legal basis: Article 37 of the Charity Law of the People's Republic of China. Natural persons, legal persons and other organizations that carry out performances, competitions, sales, auctions and other business activities and promise to use all or part of the proceeds for charitable purposes shall sign a donation agreement with charitable organizations or other grantees before holding the activities, fulfill their donation obligations according to the donation agreement after the activities, and make the donation public.
