What is this?
This is a curated Chinese-language glossary of secondhand marketplace slang (黑话) used on platforms like Xianyu (Goofish), Zhuanzhuan and Xiaohongshu, covering 4,000+ real-world code words with both buyer scam-avoidance tips and seller compliance-safe alternative phrasing.
Is this just a markdown list or does it include structured data?
It's a Markdown reference guide plus a fully structured JSON dataset (data/slang-dictionary.json) with stats, categories, abbreviations and entries, so developers can build their own lookup tools on top of it.
Does every term still work on the platforms today?
Each entry is tagged with a live status, showing whether a term currently works, is being spot-checked/flagged, or is already blocked by platform risk control, since marketplaces constantly update their filters.
What's an example of a risky phrase a buyer should watch out for?
'买包烟成色' sounds like only minor wear, but per the guide it actually often describes a device with a cracked shell and failing screen that could stop working at any time.
Does the glossary cover counterfeit goods and worn-out mining GPUs too?
Yes — it has dedicated entries for streetwear/luxury counterfeits (like '高A') and mining-rig graphics cards ('矿渣'), each with authentication or stress-test advice for buyers.
Is the slang specific to one platform or shared across sites?
The guide covers terms shared across Xianyu (Goofish), Zhuanzhuan and Xiaohongshu, since sellers often reuse the same evasive phrasing across China's major secondhand and resale platforms.
