Turn reference into recall

How to study 于 in context

  1. Say yú, then recall the core meaning: at, in, on.
  2. Write all 3 strokes while keeping the single-component balanced.
  3. Use it in 关于 (guān yú), meaning “pertaining to”.
  4. Read the complete sentence aloud once, then cover the translation and explain how 于 works in that context.

Definitions and traditional forms are compiled from Make Me a Hanzi, HSK curriculum data, and CC-CEDICT. Sourced example sentences link to Tatoeba; editorial examples are labeled separately. Review data sources and licenses.
