I heard rumors about it and couldn't quite believe it but here it was a toilet paper dispenser with payment via WeChat. I was lucky that my wife put 10 RMB on it foresting purpuses because otherwise I would probably need to call her to come in and pay for it.
It was 3.8 RMB and you get a small package of wet tissues. I have no idea if they dissolve as easy as normal toilet paper but I like the Japanese way with water bidets better.
On the way out I also realized that there is another dispenser for normal toilet paper at the entrance -you also pay for it with WeChat, not sure probably it's cheaper, sneaky.- ah no it says scan it for free paper, I guess it's played by advertisement.
Anyway cool mall here l, very flashy in the middle of Changchun by the train station.
This probably would have been a better solution.
Or bidets and you get some toilet paper to dry off.
