The Unusual Bus Stop Mystery Solved

I had noticed this bus stop, just off Hongxing Square, for Bus #20 where people lined up to wait for the bus -- unlike any other bus stop in Chengdu. Until today, no one could tell me why only at this bus stop did people line up in an orderly single-line. Turns out the answer is simple: This bus stop is only for Bus #20, so everyone is waiting for the same bus; unlike other stops where several buses may stop and the folks don't know who is getting on which bus. Also, this is the beginning of the route for Bus #20, so many people get on at this prime location in downtown Chengdu, so there is always a line. Mystery solved!
