Identity consistency (strict):
• @konglingchao : same face + same hairstyle (same glasses shape if present).
• @konglingc.monochrome : same face + same long straight hair with full bangs.
• The three professors keep consistent faces/hair/outfits within this clip.
Wardrobe (appropriate, professor/host):
• @konglingchao : formal, professor-appropriate smart look; dark suit or dark blazer over a black turtleneck (black high-neck sweater), neat and understated.
• @konglingc.monochrome : elegant studio look (as reference), neat and fashionable.
• Professors: simple formal studio attire.
Captions (minimal, face-safe):
Hangul ONLY, one short colorful 꽃자막 at the very bottom (lower-third safe area), MUST NOT cover faces. No Chinese/English.
Language / Voice rules (important):
• @konglingchao speaks ONLY Mandarin Chinese, using his own natural model voice (no dubbing, no other languages).
• @konglingc.monochrome speaks mainly Korean; if she speaks Chinese, it is short and noticeably non-fluent (slightly awkward), but still polite.
Action (opening, clear):
@konglingc.monochrome greets viewers for New Year briefly in Korean, then welcomes @konglingchao with a Korean honorific (“공 교수님/콩 교수님”) and introduces the topic (China–Korea ancient architecture comparison). @konglingchao replies with one calm Mandarin opening sentence (his natural voice). Professors nod.
Camera: one continuous wide-to-medium shot, gentle push-in toward @konglingc.monochrome and @konglingchao .
Negative: no extra UI, no logos, no readable papers/labels, no music, captions never cover faces, no Chinese/English on screen (Hangul captions only).
