In addition to their own public figures, a large part of the reason is that many international programs are sponsored, and sponsors will stipulate what kind of clothes artists wear, so when they put on their own clothes, they will be coded by the program group to cover up the logo of the clothes, so as to achieve the effect of broadcasting the programs or promote their products. Therefore, only the stars wear private clothes, or don't wear according to the sponsor's wishes, will they be marked with logo.
Of course, this kind of thing will not only happen to Hua Chenyu, but also to many stars, or the clothes of current traffic stars. There is no need to let them spread their clothes and cause such a big response.
Because we know that girls in idolize are terrible now, they will buy a lot of the same models about their idols, or there will be some peripheral things when they play TV dramas, giving some benefits to girls in idolize, so that they can feel like wearing the same clothes and accessories as their idols. Therefore, it is a good thing for idols to participate in the program with logo, not only for sponsors, but also for the stars themselves.
