In February, 50% of all Steam users were Chinese-speaking due to Chinese New Year and certain popular Chinese games

Valve has released its latest Steam Hardware and Software Survey, which revealed a 20.88 percent increase in Simplified Chinese-speaking users in February 2025, making up half of the entire userbase.
As Automaton noted, February usually brings an increase of Chinese users to Steam as it coincides with Chinese New Year holidays. However, this year's increase was significantly higher than usual - 2024 saw an equivalent increase of 7.26 percent.
