I think the audience loves this pair of CP, and what makes the audience feel distressed is their interpretation in the movie. Hu Jun plays a rich boy named Han Dong, who never takes his feelings seriously. He and Liu Ye's poor student Lan Yu came together because of an accident. Later, after Han Dong got married, they had to separate. After Han Dong failed in business, Lan Yu spared no expense to help him. But no one expected that the film ended in a tragic way. Perhaps tragedy brings people more artistic shock. In short, the audience was very impressed with this CP.
I think when the film was released more than ten years ago, the audience liked them because of their interpretation of the characters in the film, which made the audience like them more than ten years later. I think this is inseparable from their deep brotherhood and personality in real life. In the third season of Where's Dad Going, the audience met again on TV. As expected, everyone liked their looks very much, and even their son showed the audience a little pink. To tell the truth, when I saw "Where is Dad Going", I had a crush on this cute little CP.
What makes the audience feel happiest is that both of them have a happy and complete family, and they both have children. Now they are really good friends.
