A 70-year-old man wearing reading glasses and a greasy coat is reading a newspaper, while "I" is wearing a beautiful trench coat. These physical descriptions are not serious, but vivid descriptions are impressive. Comparing a simple old man with "me" in different situations and moods laid the foundation for the following elderly people to donate money and highlighted the noble sentiments of the elderly.

A down-and-out old man will give most of his living expenses to those in need, and "I, a woman who spent thousands of dollars on a bottle of CD perfume, love myself more and more, but I am more and more heartless to others". The old man woke me up with his actions, and "I" felt uneasy about my indifference and selfishness.

8. Learning is like a fertile soil. As long as you work hard, you will have fruitful results. If you are lazy at work, you will regret when others dance the poor harvest.

9. Victory includes Coptis chinensis and honey. Yellow wins before swallowing, honey wins before tasting.

Because we have countless shortcomings, we must overcome them. Every shortcoming is accompanied by a big failure, so we should make full use of our own advantages to make up for our own shortcomings.

Because the essence of diligence is to save and seize every minute around you, if you want to succeed and learn something, you must cherish your season, so you must overcome time.
