I’m a Chinese Language Expert and AI Content Reviewer with 15+ years of experience across journalism, editorial review, policy communication, and information verification. I previously served as a reporter and deputy editor at People’s Daily (Guangxi Branch), where I built strong expertise in fact-checking, source verification, news writing, and editorial quality control.

In my current work, I evaluate AI-generated news content for accuracy, logic, and language quality, then provide structured feedback to improve AI model performance. I also support dataset labeling, classification, and scoring, and I focus on identifying hallucinations, misinformation, and content gaps, while assessing factual accuracy, logical consistency, language quality, and policy-related content for high-stakes communication environments.

Alongside AI evaluation, I’ve led editorial and communications responsibilities as an Office Director and Office Manager, reviewing policy documents, executive reports, and official communications to ensure accuracy, clarity, and consistency. I bring a rigorous, process-driven approach to content moderation, prompt evaluation, and research analysis—so outputs stay reliable, coherent, and publication-ready.
