Wei Gongzi heard that Zhao had a hermit named Mao Gong, who lived in seclusion among gamblers and lived in a liquor seller's house. Wei Gongzi wanted to meet these two men, but they took the initiative to hide and refused to meet him. When Wei Gongzi knew their hiding place, he secretly stepped forward and interacted with the two men, and they were very harmonious with each other. When Ping Yuanjun heard this, he said to his wife, "At first, I heard that your brother (son of Xinlingjun) is unique in the world. Now I hear that he casually associates with gamblers and wine pulp sellers. My son is just a fool. " Mrs Ping Yuanjun told these words to Wei Gongzi. When Mr. Wei sent his wife (Zhao) away, he said, "I heard that I was capable, so I failed Wang Wei and saved Zhao to satisfy my wish." But Ping Yuanjun's friendship with the people is just a feat of window dressing, not for seeking the wise. When I was in Daliang, I often heard that these two people were very talented. When I arrived in Zhao, I was afraid I wouldn't see them. People like me associate with them in case they don't want me. Now Ping Yuanjun actually thinks it is a shame to associate with them. I am afraid it is really not worth making friends with him. " So I packed my bags and prepared to leave Zhao. Mrs. Ping Yuanjun told Ping Yuanjun all these words, and Ping Yuanjun took off her hat and apologized, resolutely retaining Wei Gongzi. After Ping Yuanjun's disciples heard about it, half of them left Ping Yuanjun and joined the team of Wei Gongzi. Scholars from all over the world went to join Wei Gongzi, who invited all public guests from Ping Yuanjun to his door.

Wei Gongzi stayed in Zhao for ten years and never came home. When Qin heard that Wei Gongzi was in Zhao, he stepped up his troops to attack the east, day and night. Wang Wei was worried about this matter and sent messengers to invite Wei Gongzi to return to China. Fearing that Wang Wei would resent him, Wei Gongzi warned his disciples: "Anyone who dares to tell the messenger of Wang Wei will be put to death." All the guests turned their backs on Wei and came to Zhao. No one dares to persuade childe to return to China. Taigong and Gong Xue went to see their son and said, "The reason why my son was valued in Zhao and his reputation spread to other countries is because of Wei. Now the state of Qin has attacked the state of Wei, which is in danger, and his son has no sympathy. If Qin Jun broke the girder and destroyed the ancestral temple of the first king, why did Zi stand in the world? " Words haven't say that finish, childe immediately changed his face, ordered to prepare horses and chariots, set out to rescue wei.
