"Looking at the broken bridge at the Watergate" refers to observing the flood discharge of the Watergate Dam and whether there is a flood breach. In American history, Watergate incident is regarded as the representative of national political scandal. The "Watergate" here refers to an arch bridge in Washington, surrounded by water conservancy facilities such as Watergate Dam and Lockreed Hydropower Station.

The word "breaking defense" refers to the loss of defense of water conservancy projects, usually due to flood impact and other reasons, resulting in serious damage and loss of water conservancy buildings. In the Watergate incident, the appearance of the word "breaking the defense" also meant that President Nixon of the United States was exposed to some acts involving political shady and illegal operations.

Although more than 40 years have passed since Watergate, its influence and lessons will still exist for a long time. Whether at the individual level or the national level, we should ensure honesty and transparency, respect the legal system and public interests, and avoid self-expansion and irresponsible behavior, so as to build a more harmonious, stable and progressive society.
