Historical questions, please help me answer them

In fact, there are quite a lot of them, such as the husband is surnamed Ji, Hu Hai is surnamed Ying, most of the people before the Spring and Autumn Period are the descendants of the Yellow Emperor, and most of the descendants of King Wen are surnamed Ji, and they are not called by their surnames, so it is more weird. After the Spring and Autumn Period, surnames appeared, most of them were named after their homeland and well-known ancestors, and the names were much more normal.

Because the Han Dynasty implemented the parallel system of counties and states, the surnames of people in a place were the same, and the current hundred family surnames were gradually formed.

I don't know, celebrities are naturally different, Wu Zetian also made a special word for himself, in the early days, people sought survival and development, before the unification of Qin, who cared about cultural exchanges, maybe as it is said now, the name is just a code name, and it is convenient to call it, so people at that time didn't care very much.

At that time, there were many reasons for the name, some according to the title of the ancestors, some according to one's own location, etc.

1.Ming Dynasty people.

2.Dumping is a kind of scraper-type continuous water lifting machinery, also known as keel waterwheel, which is one of the most famous agricultural irrigation machinery in ancient China. The Book of the Later Han Dynasty records that Bi Lan overturned, and Ma Jun of the Three Kingdoms perfected it.

The overturning can be driven by hand, foot, ox, water or wind. The keel blades are used as chains, lying in rectangular long grooves, and the body is inclined to the river or pond. The lower sprocket and part of the body were submerged in the water.

When the sprocket is driven, the blade rises along the groove and sends the water out to the upper end of the long groove. In this way, the continuous circulation can transport the water to the place where it is needed, and the water can be continuously taken in, the efficiency is greatly improved, the operation and handling are convenient, and the water intake point can also be transferred in time, which can be irrigated and drained. The earliest application of chain drive in ancient China is in the overturn, which is a major improvement of agricultural irrigation machinery.

3.Guanzhong, refers to the hometown of Zhong Kui, the sage of Shifu Town, Shaanxi Province, the alluvial plain of the Wei River (Weihe River Basin) at the north foot of the Qinling Mountains in the hometown of Zhongnan Mountain, with an average altitude of about 500 meters, so there are Weihe Plain, Guanzhong Plain and other names, the north is the Loess Plateau of northern Shaanxi, and the south is the basin of southern Shaanxi and the Qinba Mountains, which is the industrial and agricultural development of Shaanxi, the densely populated area, the rich land, known as the "eight hundred miles of Qinchuan".

4.The color of the bronze is very beautiful when it is really made, it is a **-like earthy yellow, because it is buried in the soil and rusty, it turns green little by little.

5.That doesn't seem right. Bronze ware had just appeared in the Xia Dynasty, and the smelting and production technology was developed in the Shang Dynasty, producing many exquisite utensils, but they were still precious metals, because of the difficulty of smelting and production, and the high production cost, so they were mostly used in the royal family.

In the Zhou Dynasty, with the great development of smelting and production technology, its production cost was reduced, and bronze ware was further popularized, and it began to enter the homes of ordinary people from the princes and nobles, and many production tools made of bronze appeared at this time. Therefore, it is not possible to talk about the affairs of the Three Dynasties in general.

Of course, from another point of view, although agriculture at that time had developed greatly compared with the past, it still could not be compared with later generations in terms of crop varieties, farming techniques, and cultivation scope, and on the whole it was still somewhat backward. As a result, there are few types of production tools for people. In addition, bronze smelting is difficult to make, and the cost of using it as a production tool is high, so it is rare.

Another one is my guess, I feel that although the production tools made of bronze are hard and durable, they are also heavy and inconvenient to use, so they do not make large-scale production.
