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.
Happened as dated, per the source: "the Chongqing East railway station opened to passengers on 27 June 2025."
Wikipedia confirms "the station opened to passengers on 27 June 2025," an exact match to the pin's stored date.
FTNnews' own headline, "China Opens World's Largest Railway Station in Chongqing," published 1 July 2025 - just days after the pin's stored date - supports the pin's claim, though the article returned a 403 error and could not be retrieved.
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.
