The English-speaking area at least plays straightforwardly with open schemes, and quotes are widely publicized. What should be reflected upon is how much the so-called KOLs in the Chinese-speaking area have earned, and how much they get per post is all an unknown. Moreover, the number of KOLs in the Chinese-speaking area who can have a significant promotional effect is very few. Most of them don't play or research themselves, they just take the money and shout for the project.
