Quasi-easy to learn and brush questions every day. According to relevant data, its interactive live class helped tens of thousands of training institutions across the country to suspend classes during the epidemic. The live class completely simulates offline interactive scenes, automatically reserves videos, generates links, shares friends' circle, and increases institutional knowledge output. External parents can also make an appointment for the audition class of the registration institution directly on the link of the live class. So brush the questions well every day.
