     A woman came out of her house and saw three old men sitting in her front yard. She said, "I don't think

I know you, but you must be hungry. Please come in and have something to eat."

      "Is the man of the house home?" they asked. "No", she replied, "He's out.""Then we cannot come in",

they replied.

     In the evening when her husband came home, she told him what had happened."Go to tell them I am

home and invite them in!" The woman went out and invited the men in."We do not go into a house together,"

they replied."Why is that?" she asked.

     One of the old men explained that their names were Wealth (财富), Success and Love. Then he added,

"Now go in and discuss with your husband which one of us you want in your home."

     The woman went in and told her husband what was said. Her husband was overjoyed and he suggested

inviting Wealth to fill their home with wealth. And his wife wanted to invite Success; but their daughter-in-law

suggested they should invite Love so that their home would be filled with love. At last the husband said to his

wife."Go out and invite Love to be our guest."

     The woman went out and asked the three old men, "Which one of you is Love? Please come in and be our

guest." Love got up and started walking toward the house. The other two also got up and followed him.

Surprised, the lady asked Wealth and Success:"I only invited Love, Why are you coming in?" The old men

replied together: "If you had invited Wealth or Success, the other two of us would have stayed out, but since

you invited Love, wherever He goes, we go with him. Wherever there is Love, there is also Wealth and Success!"
