Line 12 in Shanghai. (Subway system)
Well, the good news is, if you ever get confused by the complicated transition system, simply hop on Line 12, you’ll find the train home…
Actually, I promise you Shanghai subway system is way better/simpler than MTA in NYC. MTA is just…out of mind, esp. on weekends, when you took the E train only to find out it’s running on F train’s in Manhattan.
