Why only China has "treacherous court official"? Other countries-there seems to be no word treacherous court official.

There are no traitors and loyal ministers in the United States, which is attributed to the short time since the founding of the United States and the revival of European culture. Without its own local culture, today's United States can basically be said to be a country with many races (except for the reported celebrities). Of course, after becoming a weak minority due to the conservatism of native Americans, early European immigrants were the main body. Even a large number of immigrants from other countries in the later period could not replace this main ethnic group.
