The inventor of paper is traditionally assumed to be Chai Lun (or Ts'ai Lun), who was the head of a royal workshop in 2nd century China.
However recent archaeological evidence suggests paper was in use in China two hundred years earlier.
Another vital ingredient was birch leaves, from which the mucilage was drained out for strengthening the paper, and giving it evenness and smoothness.
All the fibrous material, once softened, was beaten into a pulp which was said to be rather like porridge, and the birch leaf extract was added. The great thing about Chai Lun's invention was that his paper could be mass-produced.
Over thousands of years China has produced a great stream of inventions, ranging from the mundane chopstick and wheelbarrow, to sophisticated earthquake detectors and the advanced concept of bank notes.Indonesia’s Women’s Empowerment and Child Protection Ministry said it was up to individuals if they wanted to use the app because polygamy is legal as long as it can be done in a fair manner.“For us what is important is whether the women and children are protected in polygamous marriages,” the ministry’s spokesman Hasan, who uses one name, told the Thomson Reuters Foundation.
