Key takeaways
China LLMs often excel at CN↔EN marketing and product copy when you lock glossaries and style. They are not a substitute for certified legal translation. Prefer bilingual eval sets over leaderboard claims. Pair with JSON structured output for CMS pipelines (/en/articles/china-llm-json-structured-output-2026).
