Shao Qihai tagged along, insisting he knew Ji Buwang and wanted to help him celebrate his birthday too. When he saw Ji Buwang's actions and the way Mu Jingzhe was smiling so happily at his words, he felt that he was simply inferior to Ji Buwang.
Ji Buwang's birthday was held at home. At his old age, it was impossible for Old Master Ji to come over to celebrate the birthday of a junior. Only Ji Buwang would go back to celebrate his grandfather's birthday, not the other way around. Therefore, there was no one else there.
Tang Moling wanted to celebrate with Ji Buwang, but he didn't get the chance to come back, as he had been sent away to work by Ji Buwang.
On Mu Jingzhe's birthday, Ji Buwang had said that he didn't want Mu Jingzhe to work hard. This time, on his birthday, there was no need for Mu Jingzhe and the others to do anything. With everything already taken care of, all they had to do was have fun.
