If you're preparing for HSK 4 and want to sound more polished in professional Chinese, 所 (suǒ) is a grammar particle that helps you emphasize and summarize information in a formal register. This live voice lesson teaches you to use it correctly in real conversation — not just recognize it on paper.
所 (suǒ) functions as a nominalizer in relative clauses, turning a verb phrase into "what" or "that which." The structure is: Subject + 所 + Verb + 的 (de) + Noun.
The key example in this lesson is:
他所说的话很有道理。 (tā suǒ shuō de huà hěn yǒu dào lǐ。) — "What he said makes a lot of sense."
Another illustration from the lesson: 我所知道的就这些 (wǒ suǒ zhīdào de jiù zhèxiē) — "What I know is just this much."
You place 所 (suǒ) right before a verb and 的 (de) right after it, putting a spotlight on the key information you want to highlight. This pattern is more common in written and formal Chinese — meetings, reports, presentations — than in casual speech.
This is a live conversation lesson: you talk out loud with AI teacher Mei Lin in real time, by voice. Over roughly 10 minutes, you'll practice the 所 (suǒ) pattern by producing sentences like the examples above in response to Mei Lin's prompts. She corrects your grammar and pronunciation in the flow of conversation and adapts to your level.
The lesson targets exactly one grammar pattern — "Highlighting What Matters" — so you leave able to use 所 (suǒ) confidently when summarizing what someone said, what you know, or what was experienced.
You can try the first lesson free. To reinforce your writing alongside speaking, you can also print handwriting sheets with the free printable Chinese worksheet generator.
