An investigation by a reporter found that an educational app covering 3000 million students, "Class Optimization Master", is widely used in some primary and secondary schools across the country. The app records almost all of students' behavior in school, and ranks students by adding or subtracting points and evaluating them publicly.
Some school ranking results are also linked to merit. Many parents and students have new anxiety about this. Some teachers announce the cumulative situation of the addition and subtraction of points in the App to students in real time.
