At 70 years old, Jackie Chan is still a legend, but privately he is struggling with a reality many of us know: his son Jaycee Chan no longer responds to him. It has been three years since that contact was cut off. During a public appearance, Jackie Chan himself said something quite moving on live camera: no one responds on WeChat. That’s not an exaggeration, that’s his life.

The story is complicated. Jackie Chan openly admits that he raised his children with the tough methods of the Jackie Chan stunt team — there were even rules about how many sheets of toilet paper to use. After the incident in 2014, his son moved out. What was once a phone call a year became silence. Jackie Chan tried to apologize, but only received one reply: “You do your thing.”

Then Jackie Chan’s wife Lin Fengjiao stepped in as a mediator. Jackie Chan had to learn to adapt — he now cuts his thoughts into 15-second voice messages and adds a smiley emoji. His son occasionally responds with “Hmm.” That’s all. For older people, it’s hard to bend and accept this new form of communication.

The saddest part: Jackie Chan has written his last 70 years into a new book. The final page is intentionally left blank — reserved for his son Jaycee Chan’s signature. A silent waiting. And honestly, don’t you also have someone in your address book who doesn’t reply to your messages?
