‘国耻’ (guó chǐ) literally combines ‘国’ (guó), meaning ‘nation’ or ‘country’, and ‘耻’ (chǐ), meaning ‘shame’ or ‘humiliation’. Together, it refers to a historically significant event or period that brought deep disgrace, loss of sovereignty, or suffering to the nation — often tied to foreign aggression, unequal treaties, or national defeat. It carries strong emotional and moral weight, evoking collective memory, patriotism, and calls for vigilance or renewal.

This term is commonly used in historical education, political discourse, and commemorative contexts — especially when referring to events like the Treaty of Nanjing (1842), the Japanese invasion during WWII, or other moments widely taught as turning points in modern Chinese history. While formally neutral in grammar, ‘国耻’ is never used lightly; it signals solemn reflection and shared national sentiment, not personal embarrassment. It appears frequently in phrases like ‘勿忘国耻’ (wù wàng guó chǐ, ‘Never forget national humiliation’) and official memorial slogans.
