Subject + 宣告 + Event/State
宣告 (xuāngào) means "to declare" or "to proclaim," indicating a formal public announcement of something significant. It is more solemn and official than 宣布 and is often used for declarations of major events such as the end of a regime or the founding of a state. It carries a sense of gravity and finality.
