In 501 BC, Yang Hu, a retainer of Lord Ji, tried to draw in Confucius, but Confucius refused to see him. So Yang Hu sent someone to send a steamed pig to Confucius while he was not at home. Because according to the etiquette at that time, if he gave something to Confucius, Confucius should go to visit him to show respect. Yang Hu expected that Confucius would come to his house to thank him, so he could have a deep conversation with him. However, Confucius also went to Yang Hu's house when he was not at home. It happened that Confucius met Yang Hu on his way home. He wanted to avoid it, but Yang Hu stopped him and asked, "Is it benevolent to let the country be in chaos when you have unique skills?" Confucius replied, "No." Yang Hu then asked, "Is it wise to miss good opportunities when you hope to achieve something?" Confucius said, "No." Finally Yang Hu said, "Time is passing, and opportunities will not come again." Confucius replied, "You're right, I'll find a position that I can hold."
