In order to lead a happy and profitable life of retirement, after retiring, father-in-law wanna raise several doves. He thus used bamboo poles to build a small dove shed in the corner of downstairs, and cover with a net to make the shed more secure.

On one Sunday, father-in-law unexpectedly found the net was torn open a small hole. A big black cat was lingering near at hand and staring fixedly at his doves at that moment.

Father-in-law would like to repair the net with some ropes, but he was worried that the big black cat would bite away his doves once he went to fetch ropes, then he asked his daughter, who was playing happily down stairs, to watch over the shed for him for a while.

However, having seen all her friends were playing happily there, the daughter was unable to keep herself staying alone.

Then a flash of wit came to her mind, she picked up a chalk from the ground to write four striking words on nearby cement wall’猫勿靠近( Cats, please keep away from the shed)’
