  Four Seasons Hotel Guangzhou (IFC, floors in top third) held its official opening ceremonies on 23 July 2012 and press coverage presents Catch on the 100th floor as part of the launch offering; no separate Catch opening announcement found, so the hotel opening date is used (official fact sheet gives July 2012). Estimated: the exact day 2012-07-23 comes from a proxy source (registration, announcement or hotel opening) and is 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.
