The sudden pneumonia epidemic in early 2020 brought a "head-on blow" to the offline training in the education industry: many education departments across the country announced the postponement of the start of primary and secondary schools, and most offline education and training institutions across the country also suspended offline courses.

Children's art institutions can't start classes normally under the epidemic situation. During the epidemic period, providing double-qualified art courses for free, that is, the double-qualified version of thinking painting and the double-qualified version of comic plan, can not only solve the quality of online teaching, reduce the time of searching for lessons and preparing lessons, but also solve the problem that offline teachers are unprofessional and provide high-quality art education for children.
