  Most sources (People's Daily travel, one Baidu Baike entry) date Shangri-La^[2] Hotel Harbin to 1999; travel listings say 1998 and one Baidu entry says 1993, so the year is uncertain. No outlet-specific date found; the outlet is assumed to date from hotel opening. Estimated: 1999 is a best estimate and 1999-12-31 is used only as a period-end sorting date, not a confirmed opening day.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
