Richy and I were waken up at 5:00am by the road construction workers. Although we live on the 28th floor and kept the window closed, we still could hear the loud sound of worker's drilling the road. The workers slept early and they began their work early without worrying interrupting others' sleep. Usually we wake up at 6:30am because the honks of the trucks and cars just never stop since then.
There is no noise regulation in China. You can hear firework in the midnight, and big construction noise in early morning, and no policeman will stop the noise for you. Our neighborhood is a well-developed district in terms of the public facilities, infrastructures, and industries. But the cilivilization of some locals still did not catch up with the speed of modernization in this area. I saw many cars driving the wrong way on the street even in front of policemen. It was even worse in the area outside of our neighborhood. As for the policemen, some are strict, and some are lazy. I saw some policemen sit under the shadow and chat at work. Anyway, we saw many policemen on the street all the time, but very few really do their job. The only time I saw them do their job was when I was stopped by one policeman on the main street of Su-Zhou city when I made a wrong U turn which was not allowed on that street. I respect that policeman because he is strict but kind, and most importantly, he does his job without a miss.
