First, Nicholas Tse and Eason Chan met when they were young, and their feelings were not mixed with other things, so they were very deep.
When Nicholas Tse and Eason Chan met, although they had entered the entertainment circle, they didn't become popular and didn't have today's popularity. It can be said that when they met, the two entertainment circles had no fame and fortune. At that time, the feelings were relatively pure and there was no interest relationship, so I think that the friendship between two people can last for so many years and this reason is inseparable.
Second, after entering the circle, the two have different development directions, resources do not overlap, and their feelings remain the same.
Eason Chan has been developing in the music industry. Although Nicholas Tse has also released albums and worked as a singer, compared with Eason Chan, he is a scalper in the music circle. Therefore, the resources of two people in the entertainment circle do not overlap and infringe upon each other, so the relationship between the two people has never changed. If two people have the same development path and resources, I think they may not have today's intimate relationship.
Third, both of them like singing, have similar interests and have many topics, so they are so close.
When two people have a name and interest, they find that they have the same hobby, that is, singing. As long as they are together, they will have endless jokes, so their feelings will always get closer and closer. If two people have lost the same topic for a long time, they can only look at each other awkwardly and laugh or say three polite words. I really don't believe their relationship can last until now.
