The official name is 国际劳动妇女节 (International Working Women's Day), observed in China since 1949. Women get a half-day off. In recent years Chinese e-commerce has rebranded March 8 as 女神节 (Goddess Day) or 女王节 (Queen's Day) - a marketing move many feminists view critically as trivializing the labor-rights roots.
usage
Also called 三八妇女节 (三八 = March 8). In northern China slang, 三八 alone can be a mild insult ('gossipy/silly woman') - so be careful using 三八 as a standalone word.
