The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
MUME opened on Taipei's Siwei Road on 23 December 2014, the eve of Christmas Eve, according to a Commercial Times report (via LINE Today). Other sources, including Tatler Asia and the operator's own history, confirm a late-2014 opening, with December 2014 as the month; the exact day rests on that single report.
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.
