During the Warring States Period, there lived a man named Su Qin. He tried to get a job as a government official（官员）, but he failed. When he arrived home, his family looked down on him and didn't want to speak to him. His sister-in-law（嫂子）treated him worst and even refused to offer any food to him. Su Qin felt very sad, but he didn't give up on himself. He studied hard everyday, and finally came up with the "zong-heng principle"（纵横之术）.
Later on, Su Qin traveled to many states and explained his idea to the kings. He told them that small states should work together to fight against the strong state, Qin. Luckily, He persuade other states to accept his idea. And he became the prime minister（丞相）of them.
One day, Su Qin passed by his hometown. His parents, brother, wife and sister-in-law all came out to welcome him. When he saw his sister-in-law, he laughed. He still remembered how she treated him in the past. Then he asked her, "You were rude to me before. But why do you look up to me now?" His sister-in-law answered, "You are an official now, so I dare(胆敢）not treat you like before.
This is the story of the Chinese idiom qianjuhougong (前倨后恭）. It is used to describe that someone treats person badly at first, but later respects him because of his high status(地位).
