In ancient times, the tools used to polish jade articles included saw-shaped tools, water stools, thallions, diamonds, jade carving knives, bows, and so on. Saws were mainly used to cut jade materials. Most of them were made of metal, but some were made of animal and plant veins. Two people were needed to push and pull the saws, and a pot filled with jade sand was placed on the saws to assist in the cutting. The saws were first seen during the Liangzhu culture period. The water stool was a jade grinding tool that appeared around the Sui and Tang Dynasties. Its main body was made of wooden frames. Thorium tools were tools used to cut and polish jade. They were divided into two types: side thorium and grinding thorium. The main material was iron. Diamonds were divided into solid diamonds and tube diamonds, which were used to make holes in jade ornaments. Jade carving knives were used to carve patterns on jade. They were harder than jade and were usually carved with diamond inlaid blades. The bow was used for carving. The method was to drill holes first, then use metal wire to penetrate them and slowly grind them with jade sand. It had already appeared in the Shang Dynasty. The tools used to polish jade in modern times included electric jade grinders, cranes, ultrasonic waves, lasers, etc. There were also tools such as diamonds used to polish jade. Commonly used grinding tools were iron thallions, treading thallions, rolling eyes, date pits, trumpet heads, grinding rods, sharp needles, sand drills, and so on. Modern iron thallions were shaped like saw blades, with a hole in the middle for fixing on a rotating shaft, surrounded by a circle of emery, used for cutting small jade materials. Treading thallions were disc-shaped saw blades, with emery powder around and on the surface of the plate, which was a grinding tool. Rolling eyes were called rolling eyes in Suzhou jade carvings, rolling thallions in the north, and small rolling eyes were also called nail thallions. The shape of the jujube stone-shaped grinding head was like a jujube stone, with two sharp ends and a bulging middle. The horn head was similar to the grinding rod, which was a variation of the cylindrical grinding rod. The front was big and the back was small. The grinding rod was a cylindrical jade-grinding tool. The body and one end of the rod were coated with emery powder for grinding jade, and the sharp needle was shaped like a needle for polishing jade. Read more exciting novels for free

Looks without social status

The following is an English essay on looks without social status: **Appearance without Social Status** In our society, there are people from all walks of life with different social statuses. However, when we simply talk about appearance regardless of social status, we can find a great variety. Some people may not have a high social standing, but they have unique and charming looks. For example, there are hard - working laborers. Their faces might be tanned by the sun, with deep lines carved by years of toil. Their hands are rough, but their eyes often shine with simplicity and honesty. On the contrary, not all those with high - end looks necessarily have high social status. There could be ordinary people who are born with beautiful features like big bright eyes, a straight nose, and a warm smile. They may wear simple clothes and live an unpretentious life. Appearance should not be a measure of one's social status. Everyone, whether they have a so - called "glamorous" look or a more "ordinary" one, should be treated equally. We should respect the individuality of people's looks and not make unfounded associations between appearance and social status. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
