Currently watching DOTA2 major (second most important events after the DOTA WC) and gaming bans seem to have utterly decimated the Chinese DOTA2 scene. China used to be the strongest region in the game - yes, they did not always win The International (essentially, WC for DOTA2) but they always were consistently top tier and had many teams in top 6: TI 1 (top 2, top 6), TI 2 (top 1, top 3-5), TI 3 (top4-6), TI 4 (top 1-2, top 4-5), TI 5 (top 2-5), TI 6 (top 1, top 5), TI 7 (top 2-4, top 6), TI 8 (top 2), TI 9 (top 3, top 6), TI 10 (top 2, top 4, top 6), TI 11 (top 4-5). So even in the worst year, they were able to produce a top 2 team or get 2 teams in top 6 of important events.
This season, most of the older players who were winning those places have retired or are past their prime but there's zero influx of fresh blood. I see mostly dudes who used to play on tier 3-4 level but now they are playing in tier 1-2 Chinese teams and the results are horrendous - they barely get out of group stages and there are zero Chinese teams in top 6 of two last major tournaments. Not only that, the scene is plagued by match-fixers and two Chinese pro teams recently got permanently banned from all competitions for that, one of the teams was EHOME who has finished in top 6 of TI multiple times in the past. Such a sad thing to see, used to cheer for Chinese teams since DOTA2 became a thing and started the yearly TI events
