Lei Zhenshan of the Shoulian Zhineng hygiene

company in Tianjin explained that “we brainstormed

many options, such as fingerprints, infra-red, and facial

recognition. Eventually, we went with facial recognition,

because it’s the most hygienic way. Before entering a

restroom in the park, visitors must now stare into a

computer mounted on the wall for three seconds,

before a machine dispenses a sheet of toilet paper,

precisely two feet in length. If they require more, they

have to wait, because the machine will not dispense a
second length of paper to the same person for nine

minutes.”

Some visitors have complained that a hi-tech toilet

paper dispenser does not befit the majesty of the

Temple of Heaven, which is a Unesco World Heritage

Site. But sixty-three-year-old visitor Qin Gang agreed

that “stealing toilet paper is a very bad habit. Some

people are eager to exploit public services, and maybe

we can use technology to change how they think. But

the sheets of paper are much too short.” (2)
