Ren He decided to extend an olive branch to Zhang Ming mainly because of a comment Zhou Wumeng made over the phone: Zhang Ming now only wants to pursue making something meaningful; money has become a secondary concern.
In fact, in most jobs in society, the pressure of sales roles is the greatest. Because you can slack off in other work: administrators can get by vaguely, human resources are trickier but still manageable, planners can slack, even technical staff can... But salespeople have a hard time fooling their superiors because it all comes down to hard targets. The amount of money you make is the amount you make; you either meet your targets or you don't—those are your two options.
Zhang Ming and his colleagues, as directors, are no different. In his past life, Ren He got to know some celebrities because of his job, organized two Jay Chou concerts, met Jay Chou several times, had tea with Xu Ke—but after drinking, Xu Ke probably forgot who he was.
