i got a phone call this afternoon from a friend in another city thousand of miles from shanghai, my friend asked me for help,“i can't find a restroom nearby, what should i do?”. i replied immediately, “find a cab and ask the driver to take you to the nearest hotel”
a few years ago, it's hard to find a rest room in some parts of shanghai. like many others, i have encountered occassions of embarrassment. but shanghai people are smart, they find in places with no public rest rooms, there are many 5-star hotels, and there are many rest rooms inside of those 5-star hotels.
portman shanghai, the 5-star hotel invested by american money and hosted visiting american presidents like bill clinton, is my favorite. because the hotel is in a perfect downtown location, i believe many people visited the 5-star hotel for the same reason.
without doubt the hotel was unhappy with those non-guest visitors and they got a great idea - lock the rest rooms and give every company and guest a key to those rest rooms. great idea! but people are still coming, they just follow a guy who has a key into the rest room. people name those rest rooms as“bill clinton's rest room”(no bad intention involved).
why i played chinese chess in “bill clinton's rest room”? here is the story:
like others, one day i followed a guy who has the key into the rest room, but when i finished my job, i found the door was locked from inside, couldn't open without a key! and the guy who has the key has gone!
luckily there was another unlucky guy, and luckily again, he took with a mini chinese chess, and we played chinese chess in “bill clinton's rest room”.

now the municipal government built a lot of rest rooms here in shanghai, and perhaps in order to appease people's yearn for“bill clinton's rest room”, they built some “5-star rest rooms”equipped with good facilities imitating those of a 5-star hotel.
