Bilingual Architecture: Run CN & EN from One Admin

Most "bilingual websites" are two systems taped together: content drifts, styles diverge, SEO fights itself. AiTion's architecture is bilingual at the data-model level.
Content-level bilingual
Every article and category is "one record, many translations": CN and EN versions keep independent titles, summaries, bodies and SEO fields — separate yet naturally linked.
UI-level bilingual
Buttons, hints and form copy are maintained per locale, and the admin supports overriding default copy per language — that's exactly how this site's homepage hero was customized.
SEO-level bilingual
Locale versions live on separate paths (/zh-CN/... and /en/...), and the system emits hreflang with x-default automatically, so Google and AI engines understand the language relationship precisely.
Experience-level bilingual
Visitors switch language in one click while staying on the current page; first visits match the browser language automatically. Two worlds, one admin.
