Talk about conflicts

When I was a child, I had a story: I sold a weapon with a spear and a shield. When I sold a spear, I said that my spear was the sharpest ,; at the same time, when he sold the shield, he said that this shield is the strongest shield, and there is no thing to be able to penetrate, without any congratulations.

At this time, a bystander said: attack the son with a spear.

What can we learn in this story? Whether to buy things is the kind of "Little smart" by the onlookers"

Think about it. This bystander is the saddest person. He is the smartest and the most annoying. Why? If you don't talk about your business, you may be confused about your progress. We can see the xuanjicang. Why not combine the contradictions? Maybe whether it is war or business, this person must be named in the history book. It is a trivial matter, and the key is to promote social progress.

Smart people are always playing their own smart, and smart people are always benefiting others.
