How to Write 蹭 (cèng) — Meaning “to rub against; to scrape; to get for free”

Imagine you are at a free buffet (蹭饭), and you keep rubbing your shoes against the floor to hide your awkwardness. The left side 足 looks like a shoe print, and the right side 曾 sounds like "zen" — think of calmly rubbing your feet while eating for free.

The character has 19 strokes, so be careful not to rush. The left radical 足 has a final horizontal stroke that should be slightly shorter than the bottom of the right part 曾. A common mistake is writing the top of 曾 as 日 (sun) instead of 日 (day) — both look similar, but in 蹭 the top is actually 日 (day) with a closed bottom.

All three have the foot radical 足, but they are used in very different ways. 蹇 means "lame" or "difficult" and often appears in classical contexts, while 蹈 means "to step" or "to tread" and is used in formal phrases like 舞蹈 (dance). In contrast, 蹭 focuses on rubbing, scraping, or getting something for free — it is more casual and everyday.

蹭 is very common in spoken Chinese, especially in the phrase 蹭饭 (to get a free meal), which describes someone who joins a meal without paying. You can also use 磨蹭 to mean "to dawdle" or "to move slowly," and 蹭破 to mean "to scrape the skin." The character carries a slightly negative or humorous tone when describing someone taking advantage of a situation.

Common words containing 蹭 include: 蹭饭 (cèng fàn) — to sponge a meal; to get a free meal; 磨蹭 (mó cèng) — dawdle / loiter; 蹭破 (cèng pò) — to scrape (skin); to graze.
