A friend once said in an interview that they were like close comrades-in-arms, a revolutionary friendship that they worked hard together. How could it be explained clearly in a few words what the three of them experienced at that time? . Some concerns do not need to be expressed, and some friendships cannot be replaced. Nicky Wu once said, three people, three personalities. What we see now is nothing more than what we know from the media. How can we know what they are thinking in their hearts. As long as everyone is doing well, that's fine. The brotherhood between the three of them is the one that makes me cry the most.
