China's ancient inventions.

Xin Qiniang, who invented the resin lamp (Kongming Lantern) as a signal lamp in the war in the 20th century A.D./KLOC-,was the first time that China people used a hot air balloon. At the same time, the lantern was invented, which was the ancestor of aviation gas turbine.

In ancient times, riding lanterns were called pan-pot lanterns (Qin and Han Dynasties), fairy candle, Zhu dew lanterns (Tang Dynasty) and riding lanterns (Song Dynasty), which were the characteristic handicrafts of China and one of the traditional holiday toys. Common in New Year's Eve, Lantern Festival, Mid-Autumn Festival and other festivals. Also known as lanterns and string lights. Weave horseheads and ponytails with bamboo.

The brightly colored paper tied to your body has now been replaced by silk. In the past, the Lantern Festival was usually held on festive days such as the Spring Festival. It consists of 20 children aged 65,438+065,438+0-65,438+04. They sing and dance, and form different formations according to the rhythm, which means happiness, wealth and harvest.

2. Compass

China is regarded as the country that invented the compass in the world. The invention of the compass is the result of long-term practice and understanding of the magnetism of objects by the working people in ancient China. Due to productive labor, people came into contact with magnetite and began to understand its magnetism. People first discovered the property that magnets attract iron, and later discovered the directivity of magnets.

After many experiments and studies, a practical compass was finally invented. The earliest compass was made of natural magnets, which shows that the working people in ancient China discovered the attraction of natural magnets and their iron very early.

According to ancient records, as early as the Spring and Autumn Period and the Warring States Period, the productive forces developed greatly, especially agricultural production, which promoted the development of mining and smelting industries. In the long-term production practice, people know magnets from iron ore. The earliest compass was Sina.

Step 3 make paper

Papermaking is one of the four great inventions in China and an outstanding invention in the history of human civilization. China is the first country in the world to raise silkworms and weave silk. In ancient China, the working people spun silk from superior cocoons, and the remaining evil cocoons and diseased cocoons were made into silk floss by bleaching. After floating, some residual flocs will be left on the mat.

When the flossing frequency is high, the residual flossing on the pad will accumulate into fiber sheets, which can be peeled off after drying and can be used for writing. This kind of floc is called "He Qi" or "square floc" in ancient books because of its small number of by-products. It can be seen that the origin of papermaking in China is related to silk floss.

4, gunpowder

Gunpowder was invented by an ancient alchemist during the Sui and Tang Dynasties in China, and it has been 1000 years. The study of gunpowder began with the ancient Taoist alchemy. The ancients refined Dan medicine to live forever. The purpose and motive of alchemy are advanced, but its experimental method still has some advantages, which eventually led to the invention of gunpowder.

Although alchemists have mastered certain chemical methods, their direction is to seek elixir of life, and the invention of gunpowder is a by-product. An alchemist usually "crouches" sulfur, arsenic and other toxic stone medicines before use, and "crouches" means surrendering. The process of losing or reducing toxicity is called "reducing fire".

Step 5 print

China was the first country in the world to invent printing. Early printing was to carve pictures and texts on wooden boards and print them with ink. This method is still used in woodcut watermark painting, which is collectively called woodcut printing (also known as woodcut printing). The predecessor of woodcut printing is the popular seal cutting in BC and the rubbings and inscriptions that appeared later. After the emergence of production technologies such as papermaking and inkmaking, block printing technology was gradually invented.

According to the research of historian Deng Guangming, block printing was invented in the Tang Dynasty and was widely used in the middle and late Tang Dynasty. Although movable type printing was invented in Song Dynasty, block printing is still widely used.
