PaperPaper was invented by a worker named Cai Lun in 105 AD.in the Han Dynasty. Instead of making it out of trees like they do today, they did a different method than today. The material was pounded until it was smooth. Then, liquid was added tothe mix to make pulp. Next,the pulp was spread evenly on top ofa screen, which let the liquid drain out.The dried pulp was paper.Paper came in use later after it was made for more than writing.Other things were made like toilet paper, paper money.

Woodblock PrintingNext time you are typing a report or anything on your computer,and about to print the paper, now you will know the Chinese inventedit about 2,000 years ago. But the kind we are talking about now iscalled woodblock printing. Woodblock printing was very simple.People first wrote out the text or whatever they wanted to put ona sheet of paper. After that, they pressed the inked part on top of a wooden block, leaving a mirror- version of the text. The carver had to make sure all the text was turned around so it would makesense on the woodblock. Then, the inked part was carved away.

Back then, silk was expensive. Poor people didn’thave silk. If you did, it was beautiful. Silk was used for so

many things besides clothing, from men’s ties to embroidery.The Chinese didn’t want the rest of the world to knowabout silk. So, they kept silk a secret for many years. Silk ismade from silk worms. Did you know it takes 40,000 silk worms to make just 12 pounds of silk?

Do you have a kite? If you look at one, can you imagine that the Chinese people invented it so many years ago?

Yes they did. Long ago, the Chinese invented kites to scare away evil spirits and to measure distances, to test wind and to scare off enemies at battle. There are so many shapes and sizes and different colors of kites. To this day, people use and enjoy kites all around the world and especially in China.
