How to treat the group behavior of international students?

Most people will hold groups, including Europeans, East Asians, Indians, Indians, Latinos, local whites, local blacks and local Asians, but it is really rare for East Asians, especially China people, to be ashamed of holding groups. I think the fundamental reason is that China has been closed for a long time because of its geographical location and national strength. For example, it has not been strangled by European nations because of its geographical location, like the Middle East nations, nor has it been colonized by the West for hundreds or even hundreds of years because of poor countries, like India and Latin American nations. There are no foreigners in the life of ordinary people in China, so they are generally very strange and ignorant about the foreign world. This ignorance is reflected in other countries' economy, culture, race and other aspects, which leads to China's blind arrogance to the outside world before opening its doors, and its blind worship to the outside world after being forced to open its doors voluntarily. In fact, in the final analysis, it is because of its ignorance of the outside world.
