Have you ever had dinner in a Chinese restaurant? If you have, you probably noticed how loud the diners are! The atmosphere is bright with lots of lights on. These Chinese people eat, chat and laugh, merrily. This is in contrast with dining in a western restaurant. The light is dim. The diners eat quietly. If you have taken a flight with many Chinese tourists, you will find yourself surrounded by a happy buzz. But if sit with many western people in an airplane, you will notice that nobody is talking to each another. This brought lots of westerners' comment: "ah, Chinese people are so loud".
