hotel_name_en / hotel_name_zh
酒店名称（英文/中文）
Full property name in both English and Simplified Chinese, normalised across Ctrip, Qunar, Fliggy, Meituan, and Booking.com. Dual-language field is a China-specific requirement as Chinese OTA names frequently differ from international brand names in ways that cause deduplication failures without explicit bilingual matching.

china_star_rating / ota_score
中国星级评定 / OTA评分
Official China National Tourism Administration (CNTA) star rating (1–5 stars, with Diamond ratings) alongside platform-specific guest scores from Ctrip (4.8/5 scale), Meituan, and Qunar.

foreigner_registration_flag
外籍住客登记标志
Indicates whether a property is licensed to accept foreign passport holders — a China-specific compliance requirement under Public Security Bureau (PSB) regulations.
