When Zhao Qibing drove to the Hidden House Yu's Villa that night, the Hidden House Yu gave him some face, and Yu Xiaochen came out to welcome their "nephew" Zhao Qibing.
At the dinner, Zhao Qibing saw the crippled Yu Shan. Compared to Zhao Qibing's success, Yu Shan was in a worse state. The two were both participants in a power struggle, but Zhao Qibing was the winner, and Yu Shan was the loser!
House Yu's future was destined to be Yu Bing 's, and Yu Shan was just a stepping stone for him to get to the top. The only reason he could come to this dinner was because there weren't many descendants in house Yu-only Yu Ning and Yu Shan were at home, and the others were all disciples and descendants of the elders. They weren't from the main branch of house Yu, so they couldn't come.
Of course, elder Yu didn't attend the dinner-he didn't have to give Qibing any face. With Xiaochen here, he was already giving the Hidden House Zhao enough face.
