The publishing system can replace or extend this body while keeping the same route, site skin, category context, image placement, disclosure rhythm, and related-resource path.
Editorial note
This route is preserved from the old Digioptimal archive. Future XingTu updates can replace or extend this body while keeping the same URL, category coverage, and publication skin.
