Why do schools and education departments repeatedly reduce the burden on primary and secondary school students, leaving school at 2: 50 pm, and let so many training institutions of off-campus education groups (listed companies) exist and flood, so that they can increase the academic burden of primary and secondary school students and increase the mental and economic burden of parents? At present, primary school students go to two unrelated schools, one is a government school and the other is a school of an off-campus training institution, and they study two sets of textbooks at the same time. Since the teaching materials of off-campus institutions are good, why can't we use national teaching materials? Since we want to reduce the burden on students, we should ban off-campus training institutions and not allow them to exist! What is education for? Please don't forget your initiative, Ministry of Education, tell the truth and do practical things. Don't set a bad example for children by playing tricks, and don't "reduce" the institutions that make up lessons for children and train them outside the school. If off-campus training institutions are the product of reform, then this reform is wrong and harmful!
