When introducing paperweights, paperweights and scales are often confused. Actually, the ancients didn't. Although the uses belong to the same category, the names are different due to different equipment types. Most paperweights are three-dimensional shapes of rabbits, horses, sheep, deer, toads and other animals. Paperweights are small in area and heavy in weight, and the materials are mostly jade, ceramics, copper and crystal. Scales usually appear in pairs, especially rectangular scales, which are usually in pairs. This kind of ruler is common, so it pays great attention to surface decoration. Someone writes couplets on a ruler, drawing one word at a time, etc. The left and right sides are connected to form a whole picture, but they can be divided into separate pictures.
As the name implies, rulers are generally made of dense and heavy wood, such as mahogany, ebony, sandalwood, etc., especially in the Ming and Qing Dynasties. Generally speaking, rulers have more practical functions than paperweights. Later generations love to use copper rulers. First, it is easier to get copper, and second, it is heavier. Generally speaking, there is a pair of scales, the technical means are generally carving and embedding, and more are couplets. The content is mostly inspirational, diligent, cheerful and entertaining. As for Fangzhen Town and Yuanzhen Town, I think they belong to the category of ruler, which is the extension and expansion of ruler's function, and its function is mainly as a tool for copying inscriptions. During the enlightenment of ancient calligraphy, people paid attention to copying first, which was effective in mastering the shelf and style of the original post. Today's people often don't know exactly, and often never take a detour. But the paper used by the ancients was not as transparent as it is now, and there were all kinds of auxiliary equipment. So the paper must be pasted on the original post, so as to see clearly the order and exquisiteness of the strokes below. So the square town and the round town were invented to hold down the four corners of the paper, which saved a lot of effort and trouble.
Modern people collectively call paperweight and ruler paperweight, which is the result of social development. Therefore, paperweight, paperweight, book town are all called paperweight.
So your idea of giving people away is to give them a pair if they cater to the names of modern people.
If you are the older generation or people with deep traditional culture, you will get a three-dimensional, small and heavy one (these two aspects are the first), and the materials are mostly jade, ceramics, copper, crystal and so on. What you presented was an ordinary rectangular ruler. If you work hard on the surface decoration, give it a pair.
