Toilet paper is a soft paper product used to maintain personal
hygiene after human defecation or urination. It differs in
composition somewhat from facial tissue, and is designed to
decompose in septic tanks, which some other bathroom and facial
tissues do not. Most septic tank manufacturers advise against
using paper products that are non-septic tank safe. Different
names are used for toilet paper in countries around the world,
including "loo roll/paper," "toilet roll," "dunny roll/paper,"
"bog roll," "bathroom/toilet tissue," "jacks roll" or just
"tissue." Although paper had been known as a wrapping and
padding material in China since the 2nd century BC, the first
use of toilet paper in human history dates back to the 6th
century AD, in early medieval China. In 589 AD the scholar-
official Yan Zhitui (531–591) wrote about the use of toilet
paper: During the early 14th century (Yuan Dynasty) it was
recorded that in modern-day Zhejiang province alone there was an
annual manufacturing of toilet paper amounting
