They have a deeper understanding of life and a more thorough understanding of the world. In their mouths, a motto is often not just a sentence, but contains profound philosophy and the true meaning of life.

2. For example, the motto "Time is not forgiving, but time flies by" may be just a common expression for young people to express their feelings about the fleeting time. However, for the elderly who have been weathered, this sentence has profound meaning. They have experienced the precipitation and baptism of years, and deeply realize that time is ruthless and life is short.

3. Another example is the motto "Be contented and happy", for young people, it may be a summary of their attitude towards life. However, for the elderly who have been through hardships, this sentence has a more profound experience. They have experienced the ups and downs of life, know how to cherish everything they have, and do not blindly pursue material satisfaction.
