Li Ao wrote a limerick about the waves before and after the Yangtze River. "The waves behind the Yangtze River push the waves before, and the waves before die on the beach. When the scenery of Houlang can last, it will be different in a blink of an eye. "
The waves behind the Yangtze River push the waves ahead, and each generation is not as good as the next.
The back waves of the Yangtze River push the front waves, and a new generation wins the old ones.
The waves behind the Yangtze River push the waves before, and the new people in the world chase the old ones.
The waves behind the Yangtze River push the waves before, and today's people are better than the ancients.
In other words, with the development of society, people will be better than you, and the people behind will always surpass the people in front.
Otherwise, what will society develop into? .
