Chongqing’s classic river-mouth lesson sits here: the Yangtze and the Jialing meet at the tip of the Yuzhong peninsula. Maps draw a neat V; on the pier you get sideways wind, silt smell, and sometimes a faint color seam before the currents finish arguing.
汇 is the useful word — confluence, gathering — even when the board you photograph only shows 朝天门. Notice mornings when mist soft-erases the far banks: towers go gray, but the merge and the rail stay. That body sense is geography, not night-skyline paste.
Cruise horns and embarkation lines belong to the same tip; they do not rename the water. If you only shoot gangways, you miss why this gate sat where two rivers already chose to share a bed.
