Have you talked with those who take 2 hours to go to work, those who have no hope of buying an apt even they work hard, those who can not find a daycare for their kids, those who can not find a good school for their kids?
Have you been to an shared apartment by the workers, have you taken the subway at rush hour, have you been sick and gone to the hospital, have you tried to send kids to school every morning and take them home every evening?
Have you worried about the air qulity, the safety of the food, the medicine you are subscribed or treatment you received, how your kid will find a good job in Beijing?
You have to get in contact with the ordinary working people there.
By the way Beijing is growing now, in fifty years she will run out of warter, crowed with people, too big to function with all kinds of urban desease. I am agree with you that Toronto is way behind Beijing in that sense.
