In addition, venue services are mainly for private schools. Schools are generally funded by the government, and the government distributes houses without venue services. General private teaching institutions, such as private kindergartens and private higher vocational colleges, need to apply to the government for approval to build their own school buildings or rent teaching venues from venue service providers.
