Why do you say that Chengdu's secondary school exams are heavily internalized
Because of the huge influx of population in Chengdu in the past two years.
It took Chengdu 50 years before. Only to double its population from 5 million to 10 million. But the jump from 10 million to 20 million. It took him less than 20 years. So many people crowded into it. The roll also became a foregone conclusion.
