I don’t know if I have an answer on Chinese tourists beyond I think most East Asian tour groups following the person with the flag is kind of funny.
That said, China and Chinese people are wonderful. Many of the cultural standards are just different but even more may be more civilized than the west. For example, putting family before all else, a love for cleanliness, home and person hygiene, shared meals, always willing to pay for your friends, taking care of those who take care of you (guanxi), etc.
