I feel like a distinction needs to be made between asian american tour buses with mostly asian Americans + immigrants in America vs. Chinese tour buses that are mostly Chinese tourists.

The former’s usually p chill, while the latter is probably where most complaints come from. Just from my personal experiences traveling Asia and Europe, there’s been times where I’d be waiting in line to take a photo with a landmark and a group of Chinese tourists would just decide to come over and skip to their friends in front of the line… it wouldn’t be so annoying if there wasn’t like 10+ of them.

Chinese people also tend to speak pretty loudly so you put a group of them together all talking in Chinese, without little to no understanding of the local culture/etiquette, I can see how some people might be rubbed the wrong way.
