Reasons for not taking the exam

There are about more than 300 million students in our country... Assuming each student takes 5 subjects per exam... 2 sheets of paper per subject... 2 exams per year... then there would be 6 billion sheets of paper... about 4 billion meters... enough to circle the Earth 10 times... One tree can make about 1,500 sheets of paper... 6 billion is equivalent to 40,000 trees... enough to cover the whole of Beijing... For the Earth, for future generations, refusing exams is necessary. Please remember: Without buying and selling... there would be no killing!
