Sharp: When the pens are gathered together, the ends should be sharp. The pen tip is easy to write and express. Writers often refer to their pens as "bald pens", but if they are not sharp, they will become bald pens and lose the brilliance of writing. When buying a new pen, the hair is glued and polymerized, which is easy to distinguish. When checking the old pen, first wet the pen and gather the hair, then you can distinguish the sharp baldness.
Qi: refers to the pen tip after it is flattened with water. If the brush is neat, the length of the brush is equal at ordinary times, and there is no gap, then it is "ten thousand Li Qi" when writing. Because the pen needs to be completely wetted, it is difficult to check this when buying.
Round: it means that the pen is as perfect as a jujube pit, which means that the hair is sufficient. If you have more hair, you will have enough pen power to write, otherwise you will lose weight and lack pen power. The pen is perfect. The pen can turn. When shopping, there is glue in your hair. Is it perfect? Just take a closer look.
Health: the elasticity of the pen waist; Press hard, lift the pen, and then return to its original state. If the pen is flexible, it can be used freely; Generally speaking, rabbit hair and wolf hair are more elastic than wool, and books are strong and firm. In this regard, press the pen after wetting, and the front is straight and healthy.
Four virtues refer to the function of the pen itself, and we should also consider the copybook when choosing the pen. The same is true of the so-called "write his own words with a pen that someone has used". The best way to judge what kind of pen to use is to look at his handwriting directly: if the style is strong, choose Hao Jian; If you are charming and plump, choose soft; Hard and soft, and then choose double brush. The characteristics of the pen also affect the written calligraphy, thus achieving the wonderful scenery of calligraphy.
Another point is the size of the font. Write big words in capital letters and small words in lowercase letters. Small pen writing big characters is vulnerable to attack, so it can't be self-sufficient, and it's useless to write small characters with large pen.
Although there are differences between expensive brushes and cheap brushes, the key is to use them correctly.
