When I send a private message to someone on Kuaishou and mention the word Douyin, can the other party see this message?

When Kuaishou sent a private message to someone and mentioned the word Douyin, the other party could not see the message. No one else can see the private message sent by Kuaishou, only he can read it. In addition, if the private message is deleted by Kuaishou, the other party can still see it. You only delete your own records, not the other party's. If you want the other party not to see the private message, you can only withdraw it within a limited time after sending it.
