when was toilet paper invented in ancient china
Toilet paper Although paper had been known as a wrapping and padding material in China since the 2nd century BC,[2] the first documented use of toilet paper in human history dates back to the 6th century AD, in early medieval China.[1] In 589 AD the scholar-official Yan Zhitui (531â€“591) wrote about the use of toilet paper:

Chinese food proved to be a popular choice, since it was tasty, unusual, fairly inexpensive and traveled well. The oyster pail was quickly adopted for "Chinese takeout". The paperboard pails were to some extent self-insulating, and could be used for a wide variety of foods including cooked rice, moist dishes such as egg foo young and sauced dishes, though they were generally unsuitable for hot highly liquid dishes such as soups.
