How Paper Was Invented In China
The invention of paper in China is the story of how Cai Lun, an official in the Han dynasty court, developed a practical papermaking process in about 105 CE by pulping cheap plant materials — tree bark, hemp, rags and old fishing nets — into thin, writable sheets. Before this, Chinese writing was carved onto bones and bronze, brushed onto silk, or inked onto narrow bamboo strips bound with cord; a single book could fill a cart, and silk was far too expensive for everyday use.
Cai Lun's method works in four stages: soak the raw material to soften it, pound it so the plant fibres separate, suspend those loose fibres in a tub of water, then dip a flat bamboo screen into the tub and lift it out. Water drains through the mesh, leaving a wet mat of tangled fibres that is pressed and dried into a sheet. Papermaking stayed largely a Chinese craft for centuries before spreading west along the trade routes, reaching Central Asia, the Arab world and finally Europe — one of China's Four Great Inventions, alongside printing, gunpowder and the compass.

Before paper📜 How Paper Was Invented in China Look around you. Books, worksheets, exam papers, tissue, money — so much of it is paper. But about 2,000 years ago, paper did not exist. So what did people write on? Tap each one to find out why it was a problem. 🦴 Bones & shells Very hard to carve. You could not write much on one small bone. 🔔 Bronze pots Heavy metal! Words were cast in when the pot was made — you could not just jot a note. 🎋 Bamboo strips Cheap, but HEAVY. One book = a whole cartload of tied-up sticks. 🧵 Silk cloth Light and smooth — but so expensive that only rich people could use it. Tappe

Books made of sticksA book you could not carry 🎋 Before paper, many Chinese books were made of thin bamboo strips. Each strip held only one line of characters. Hundreds of strips were tied together with string and rolled up like a mat. Your turn: guess the weight! A famous Chinese official once had to read government reports written on bamboo. It is said the strips filled several carts. About how heavy could one big bamboo "book" be? About 200 g(a handphone) About 2 kg(a big water bottle) About 30 kg(a P3 child!) 🎋 📄 bamboo book paper book Pick one to tip the scale. Bamboo worked — but imagine bringing a cartload

Cai Lun's ideaMeet Cai Lun 蔡伦 👨🔬 In the year 105 CE, during China's Han dynasty, an official named Cai Lun (say: tsai loon) worked in the emperor's palace. His job included making things for the court — so he thought hard about the writing problem. 🧑🎓 🌾 🪢 🎣 "What if RUBBISH could become writing stuff?" Cai Lun's clever idea: don't hunt for something rare and expensive. Use the cheap, throw-away things lying around every village. Build Cai Lun's recipe 🥣 Tap the items you think he threw into the pot. Careful — two of these do NOT belong! 🌳 Tree bark 🪢 Old hemp rope 👕 Worn-out rags 🎣 Old fishing nets 🪙 Gold

The four stepsTurning rubbish into paper 🔨 Cai Lun's team followed four steps. Every step has ONE job: break the材料 (materials) down into tiny fibres, then join them back together as a flat sheet. 🍲 soak 🔨 pound 🧺 scoop ☀️ dry Put the steps in order Tap them one at a time, from FIRST to LAST. Which happens first?

Scooping a sheetThe magic moment: the scoop 🧺 The pounded fibres float in a big tub of water like a cloudy soup. The papermaker dips in a flat bamboo screen, lifts it up, and the water drains away — leaving a thin mat of fibres on top. That mat, dried, is paper. Try scooping Drag the slider to lift the screen out of the water. Stop when the sheet looks just right — not too thin, not too thick. vat of fibre soup This sheet is ready! ✋ Lift slowly… Why it works: water holds the fibres apart. When the water drains, the tiny fibres tangle and grip each other — like a bowl of noodles pressed flat. No glue needed!

Paper travelsA secret that travelled the world 🗺️ For hundreds of years, papermaking was mostly a Chinese secret. Slowly it spread along the trade roads — merchants, travellers and, in one famous story, captured papermakers taught the skill to new places. 🇨🇳China 📜Korea & Japan 📜Samarkand 📜Baghdad 📜Europe (a simple map — tap a stop!) Tap the stops on the map to follow paper's journey. Start by tapping China 🇨🇳. It took roughly 1,000 years for paper to travel from China all the way to Europe. Today Singapore's exam papers, story books and hongbao all come from Cai Lun's idea.

True or false?Are you sure? 🤔 Historians are careful people. Some "facts" about paper are true, and some are almost-true. Decide for each one. 3 statements to judge. Historian's tip: Cai Lun is famous not because he made the very first scrap of paper, but because he made paper good enough and cheap enough for everyone to use. That is what changed the world.

Frequently asked questions
- Who invented paper in China?
- Cai Lun (蔡伦), a court official of the Eastern Han dynasty, is credited with inventing paper around 105 CE. Archaeologists have found older scraps of coarse plant paper, so Cai Lun is best described as the person who refined papermaking into a cheap, repeatable process and reported it to the emperor.
- What did Chinese people write on before paper?
- They wrote on animal bones and turtle shells, cast characters into bronze, brushed ink onto silk, and — most commonly — wrote on thin bamboo or wooden strips tied together with cord. Bamboo books were heavy and bulky, while silk was smooth but far too costly for ordinary writing.
- What was the first paper made from?
- Cai Lun's paper used cheap, easily found materials: tree bark (especially mulberry), hemp waste, old rags and worn-out fishing nets. All of these are rich in plant fibre, which is what actually holds a sheet of paper together.
- How is handmade paper made, step by step?
- The material is soaked to soften it, pounded to break it into individual fibres, stirred into a tub of water to make a cloudy pulp, then scooped up on a flat bamboo screen. The water drains away, and the thin layer of matted fibres left behind is pressed and dried into a sheet of paper.
- How did papermaking spread from China to the rest of the world?
- It stayed mainly within China for several hundred years, then travelled westward along the Silk Road trade routes, reaching Central Asia and the Islamic world by the 8th century and Europe by around the 12th century. Cheap paper later made mass printing possible, which is why it is counted among China's Four Great Inventions.
