Firstly, we need to know that China does not accept any non-official gambling activities, except for the national sports lottery, where a portion of the purchase amount will be donated.
Let's first talk about LOL. During the S3-S4 period (when China imported a large number of Koreans), the salary system of China's League of Legends collapsed, leading to exorbitant prices for many star players. Similarly, in the early days, those who could participate in e-sports were more or less involved in shady activities (not to means those guys murder, arson, or usury, but definitely not clean). Therefore, this gambling culture spread to the LDL, with many players participating in betting, and even cases where the entire LDL team had only one player who didn't matchfix. It often happened that managers would take coaches to play Texas Hold'em. In my opinion, this is actually a reflection of the unprofessionalism of China's LOL scene.
This situation reached its peak during S7-S8, and this trend even spread to live streaming platforms, where discussions about odds were openly made. Even Chinese CS players at that time implicitly admitted to match-fixing, with some notable cases such as "tyloo's pistol round earning 500,000 RMB". It wasn't until around 2019-2020 that this trend began to ease, with more aspiring and principled players choosing to reject gambling. However, for these LDL players, their basic salary is 6,000 RMB, but they might earn 20,000 RMB for a single match, so there are still many who choose to take the wrong path. Fortunately, Tencent's education on the importance of integrity in the val is profound. Even if there are match-fixing incidents we are unaware of, they are virtually dead in the Chinese online community. Except for some foolish individuals who want to stand out, everyone abhors such behavior
