窝里斗

窝里斗 is a fixed colloquialism — literally "fight inside the nest" — describing destructive internal conflict within a family, company, organization, or even a whole nation. It is a common term in Chinese self-criticism, often invoked in the cliché 中国人就是爱窝里斗 ("Chinese people just love to fight among themselves").
