First, show your true colors and gain popularity.
There are more and more variety shows on many video platforms, such as travel and reality shows. Star artists participating in these programs can not only earn a lot of money, but also show their true nature to the audience, because most of the roles played in TV dramas are to imitate other people's lives and never let stars interpret their own lives. So in the eyes of fans, their images are almost all fake, so they can show their true feelings in reality shows, let more people know themselves and let fans know what their favorite idols are. Not only that, some fans go to see their idols. If another star performs well, then this fan may also like another person, and then this star will have more and more fans.
Second, public travel.
There are many star artists who are busy with their usual work. If they finish filming in one crew, they need to catch up with different announcements. Although I often go to different places, I have no time to wander around, so I can only finish my work honestly. However, if they take part in these variety shows, they can play all kinds of games and enjoy the beautiful scenery in different places.
Third, make friends with other stars.
There are also many stars participating in a variety show. If these stars participate, they can communicate with other different stars and sometimes become friends. When we play games together, we can communicate slowly and get closer to each other faster.
