Slogan of Nanjing Yangtze River Bridge

Under the bridge deck of the bridgehead, the words "Long live the great unity of the people all over the world" and "Long live the great unity of the people of all ethnic groups throughout the country" are written on the edge of the big fort. On one side of the small fort, red slogans such as "The people, only the people, are the driving force to create world history" and "China is a country of people's democratic dictatorship based on the alliance of workers and peasants led by the working class" are hung. These red slogans were eradicated in 1980s. When the Bridge Management Office renovated Nanpu for the 50th anniversary of the founding of the People's Republic of China, 1999 restored Nanpu slogans.
