OMO education mode is quite popular. I have studied it carefully before signing up the children. Nowadays, many educational institutions only attend classes online, which is not a real OMO education model. Mo You's calligraphy is quite powerful. All the data inside and outside the school, teachers and students' parents, short-term and long-term data are integrated with each other, and OMO teaching is truly realized. Now the children have studied for a long time, and the calligraphy foundation is very solid and grows rapidly.
