Inquiring about relevant information shows that it is illegal for training institutions to make up lessons on weekends. According to the relevant laws and regulations, schools are not allowed to occupy national statutory holidays, rest days and winter and summer vacations, and organize underage students in compulsory education to make up classes collectively, which will increase their learning burden. Kindergartens and off-campus training institutions shall not conduct primary school curriculum education for preschool minors. For specific information, please pay attention to official website for first-hand authoritative information.
