Requirements and sources
The approved publication record classifies this as freemium and expects a short experience that takes about five minutes to understand. Creator, original title, publication date, cover, source URL, and evidence links remain shared with the approved Chinese entry, so this translation does not create a second factual record. Use the original source to confirm current access, pricing, account, installation, device, safety, and regional requirements. The English copy preserves the Chinese editorial conclusion and adds no unsupported factual claims.
