Tang Yan and Liu Yifei should have met because of their work. In 20 14, they cooperated in the film "dew beauty", and their friendship began from then on. They have a good relationship, I think it is because of the following reasons.
First of all, they have the same personality. Artists in front of the camera are different from private artists. They got to know each other's personal character through their work. I feel that both of them belong to that indisputable personality, and it is natural to become friends. Secondly, some people say that distance produces beauty. Some people just can't be together all the time. If friends stay together all the time, they will quarrel over various things, but if they are both busy with work, they will meet and go shopping for afternoon tea after work, and the relationship will become more and more cordial. The nature of the work in the entertainment circle doomed that the two of them could not be together all the time.
Finally, two people don't collide. Tang Yan has been focusing on the development of TV series, while Liu Yifei has been focusing on movies. In our society, the competition is fierce, and the particularity of the entertainment circle largely determines that it is difficult for the same or similar artists to become good friends.
With so many resources, others won't have them, so friends will naturally become more and more alienated. And some entertainment companies and even economic teams will deliberately discredit or buy jobs to deal with other artists who are similar to their own artists. Even if the artist doesn't know it, the other party can't make friends with him sincerely. Of course, there are many people who are still good friends even though they look similar.
I think it's important for friends to get to know each other. Trust each other, even communicate, and get the best friends.
