Chinese in Thailand have been some of the worst offenders of bad behavior and noise. Even the Thai's who I usually bully about being noisy and inconsiderate complain along side me about the Chinese. It's surprising since there's so much Chinese influence in Thailand and the Thai's themselves are some % Chinese by ancestry.
Another large offender albeit lesser known are the hill tribes, who are largely Chinese compared to Thai's. They live on mountains so you don't get to experience them that often but if you live around them the burning, littering and insanely dangerous driving is enough to raise the blood pressure. Much worse than Thai's on fronts except for maybe loud speaker noises.
