The experts’research findings were based on first.hand information and a number of scientific experiments including a new study among the students from forty-one middle schools.To make the students understand the truth,Shanghai Education Development Co.Ltd.has produced textbooks and exercise.books made of yellow paper.The books will be used in the whole city soon.
