Although the printed house is not available to visit , there is a chance for people in Shanghai to see items printed in 3D.

In every British town, large and small, you will find shops that sell second-hand goods. Sometimes such shops deal mostly in furniture, sometimes in books, sometimes in ornaments and household goods, sometimes even in clothes.

The furniture may often be “antique”, and it may well have changed hands many times. It may also be very valuable, although the most valuable piece will usually go to the London salerooms, where one piece might well be sold for hundreds of thousands of pounds. As you look around these shops and see the polished wood of chests and tables, you cannot help thinking of those long-dead hands which polished that wood, of those now-closed eyes which once looked at these pieces with love.

The books, too, may be antique and very precious; some may be rare first printings. Often when someone dies or has to move house, his books may all be sold, so that sometimes you may find whole libraries in one shop. On the border between England and Wales, there is a town which has become a huge bookshop as well.Even the cinema and castle have been taken over, and now books have replaced sheep as the town’s main trsde.

There are also much more humble shops, sometimes simply called “junk shops”, where you can buy small household pieces very cheaply. Sometimes the profits from these shops go to charity. Even these pieces, though, can make you feel sad; you think of those people who once treasured them, but who have moved on, to another country or to death.

Although the British do not worship their ancestors, they do treasure the past and the things of the past. This is true of houses as well. These days no one knocks them down; they are restored until they are often better than new. In Britain, people do not buy something just because it is new. Old things are treasured for their proven worth; new things have to prove themselves before they are accepted.

The story of printing is a long and complex one. Before the invention of printing, the spread of knowledge depended either on word of mouth or handwriting. Both took time and errors happened easily. 2000 years ago in the Western Han Dynasty, stone-tablet rubbing(拓印) was common for spreading Confucianism or Buddhism. This led in the Sui Dynasty (581-618) to the use of carving writing or pictures on a wooden board, which became known as block printing(木版印刷).

The first book with an exact date of printing appeared in China in 868. In the Tang Dynasty (618-907), this technology was gradually introduced to Korea, Japan, Vietnam and the Philippines.

Block printing reached its golden age during the Song dynasty (960-1279) as the government encouraged the publication of large numbers of books. Yet block printing had its drawbacks. All the boards became useless after the printing was done and a single mistake in carving could ruin a whole block. In the Song Dynasty, a man named Bi Sheng carved individual characters on pieces of fine clay(粘土). Then he hardened the clay by a slow baking process, resulting in pieces of movable type.

Movable type printing has a very important position in the history of printing, for all later printing methods such as wooden type, copper type and lead type printing all developed on the basis of movable clay types. During the 13-14th centuries, This technology spread to Korea, Japan, Vietnam and Europe. Later, German Johann Gutenberg invented movable type made of metal in the 15th century.
