piyaoxuanchuan-dprv8x8mg0gx.edgeone.dev is a Chinese-language interactive game that teaches fact-checking through themes of Henan culture. It presents itself as an educational simulation — likely a school project — and nothing about the site suggests it's trying to scam or mislead visitors. There are no forms asking for personal data, no payment buttons, and no downloads. The site uses HTTPS, avoids blacklists, and loads quickly. What keeps it out of the 'trusted' category is the near-total anonymity: no contact page, no about section, and no history on archive sites. For a student or hobby project that's standard, but it means you can't verify who's behind it or how long it will stay up. If you're using it purely as a learning tool, there's little risk. If you're looking for a credible source to cite for research, the missing transparency is a limit. Most legitimate educational resources have an identifiable institution or creator — here, you'll find none.
