Chinese tourism is exactly the same here in Europe, there are large groups of them everywhere but they just go and look at the sights, go to a Chinese restaurant together and go back to the hotel for an early night. Most of them are retired couples and not exactly the type of people to cause any bother to anyone. The only time I've seen any of them in a bar is when big soccer games are on.
That's because they are relatively new to travel and not many are fluent in other languages. They travel in the safety of numbers and with a guide and translator. I remember in the 70's and 80's that the Japanese were exactly the same when they first started to travel the world as tourists. Now you see many of them in couples or pairs on their own. Give the Chinese another two or three decades to become confident with unguided travel. After all, from the end of WWII until after the end of Mao's regime in 1976 it was almost impossible for a citizen to get permission to leave and that remained difficult until well into the mid 80's.
