Founded in 2014, doll technology is an internet technology company that specializes in the service of the kindergarten system. Efforts have been made to assist the nation's kindergartens in the construction of a “booksa kindergarten”, with offices in all provinces and municipalities of the country. The company, with its specialized early childhood research and development team, provides kindergarten with drawings and e-learning materials, enriches teacher teaching, and provides parents and young children with drawing and loan services. There are more than 500 regional agents for doll technology in the country, and the "dollery" has been established in over 20,000 kindergartens. The doll-in-dollar is a direct collaboration with early learning institutions, training institutions, kindergartens, and a direct integration of online drawings into early learning institutions, training institutions and kindergartens. Embedded painting houses can save a lot of costs, reduce the pressure on shop and manual investment, and accurately deliver drawings to young friends who need them most to read, with a steady flow of customers。
