Similaity and difference-相似点与相异点,Similaity and differ

Two persons may have quite similar qualities. On the other hand, it is also true to say that everybody in the world is different from everybody else because they are not exactly the same. No two people, anywhere, are exactly alike and no two people share exactly the same likes and dislikes. Each has his strong and weak points. In order to live fully and happily, each of us needs to fortify his good points and overcome his poor ones.
