Last time I saw a joke on my mobile phone about Iron Man playing couplets with his neighbors.

There is a yard where a blacksmith lives in the east and a man lives in the west. On the 29th day of the twelfth lunar month, * * * found a blacksmith and said in a consultative tone, "Eldest brother, the Spring Festival is coming tomorrow. Why don't you put up a couplet?" The blacksmith was very happy and said, "My couplet has long been there, and it is called:' Born in the furnace, the hammer dries Kun', and the horizontal approval means' success in one fire'." * * * * said, "A new one should be put up outside the door. Let's find a gentleman and write a good one, shall we? "

The blacksmith agreed. So, they went to see Mr. Wang together, explained their purpose and asked to contact the work. Mr. Wang asked about the situation, thought for a moment, and then wrote:

Pig iron is wrought iron. When the anvil rings, the iron goes on strike.

Women are people and men are people.

Horizontal criticism: hit hard and work hard.
