Recently, I came across a pretty interesting case about the way Chen Sicheng and Tong Liya relate to each other. Many people call it something “high-class” and “well-mannered,” but I think the logic behind it is what’s truly worth pondering.

Let’s start with their child, Duoduo. At her 10th birthday party, the two stood side by side—one on the left, one on the right—both smiling very naturally. During the Spring Festival, they even took the kid to Sanya together. For the child, the divorce barely registers as any kind of impact—it’s just like her parents changed where they live. In that kind of co-parenting state, they’ve actually gone beyond the traditional concept of a “breakup.”

But the real details are right here—Tong Liya still holds 5% of Chen Sicheng’s company shares. This isn’t some emotional move; it’s a real, concrete interest tie-in. Once Chen Sicheng’s movies hit a box office of 15 billion yuan, she follows along with the dividend share. Tell me—who would actually go against their own source of wealth?

So the subtle brilliance of this “combo” is that Chen Sicheng, using his own ability, turned his ex-wife from the opposing side into a business partner. Every year they mark birthdays on schedule, and they even bring her along for company team-building events. On the surface, it looks like some kind of high-level separation, but in reality, they’re shifting a relationship from the emotional level to the business level. What ends is only the marriage certificate—what starts, instead, is an even more solid shared community of interests.

This must be the top-tier survival wisdom in China’s entertainment industry. It doesn’t rely on some grand mindset or noble sentiment—it relies on real strength and a clear-headed mind.
