First, high salary. For a star, salary is very important. Variety shows are much easier than filming, and the pay is higher. The shooting is only a few months, and you can't take time off during it. Once you ask for leave, it will delay the progress of the whole crew. Hook also admitted in "The Romantic Travel of His Wife" that he missed the day when his grandmother died while filming, and he was more free to record variety shows. Of course, stars value salary more. Variety shows pay more than filming, and the cycle is shorter. A comparison is indeed more tempting than making a movie.
Hook and Sha Yi are both senior actors in the entertainment circle, with works and strength, but now they are involved in variety shows, which still makes the audience question. Actors rush to variety shows, which really makes actors look cheap.
Second, the exposure rate is high. Actors often complain that sometimes plays that have been filmed for months are not broadcast for various reasons. These months' efforts have been in vain, and variety shows have emerged one after another, and most of them will be broadcast. There are many actors who became popular through variety shows, such as Ryan, who became famous for his humorous performance in Running Man. The actors saw Ryan's sudden popularity and felt the charm of variety shows. Of course, variety shows can also bring them the exposure and popularity they want.
Variety is definitely more attractive than filming, and actors are scrambling to record all kinds of variety. I think it is understandable that more actors will try variety shows in the future. Hook and Sha Yi are just some of the many actors. People will not give up when they make money. Moreover, recording variety shows with husband and wife files will have higher pay and greater influence, which is why Hook and Sha Yi have been recording variety shows for two years. No one will have a problem with money.
