Public welfare is the most common and concrete connotation of education. As a public service, education is no longer a pure public product, it not only

It can be provided by public schools or private schools receiving government funding.

The public welfare of education does not mean that the government is the only subject of running a school, and social groups and individuals contribute to running a school without affecting its public education attributes. Although private schools are private educational institutions, they have the same basic characteristics and functions of public services as public education. Especially in the compulsory education stage, private schools have the characteristics of "public ownership and private operation" in essence, and their social welfare characteristics are more prominent.
