Recently， part of the public toilets inTemple of Heavenlaunched "face recognition toilet paper machine"， toilet paper machine is the original intention to promote conservation paper， to avoid toilet paper waste.

It is reported that in the three public toilets at the north gate， south gate， and west gate installed a total of six machines， being set in each male toilet male and female toilet entrance， and according to the average height of men and women adjusting height. Visitors need to remove the hat， glasses， and stand in front of the screen for a few seconds， the machine will slowly eject paper at its bottom. The same person can take the paper every nine minutes， each paper length of 60 to 70 cm， and the paper has been changed from the original single-layer paper into a double paper. This can not only save the toilet paper time， but also to avoid waste.
