The Book of Ink Wheels
There are strange tools in the world, called ink wheels, which are black in color and quenched with vinegar, and their quality is very tough. The use of ink wheels is widespread.

I have heard of craftsmen who make tools, and the ink wheel is the main thing. Between the machines, the ink wheel rotates, like a star rushing away, with accuracy. Ink is used to write, and the handwriting is clear, and it will not erode for a long time. Although the years pass by, the ink marks are as new as new, which can be proved by all things and can be passed down to the world.

Or there are traders who carry ink wheels and sell them in the four quarters. Printed on the ink wheel, mark its price, show its quality, so that everyone can understand. And the seal of the ink wheel is not easy to fade, and it is difficult to be invaded by wind and rain. It is also a good help for businesspeople.

There are also artists who make good use of the ink wheel. Take the ink wheel as a pen, on the paper and silk, draw the show of mountains and rivers, and imitate the state of the characters. The ink color is appropriate, the lines are smooth and natural, and the paintings it produces are unique and cherished by the world.

The wonders of the ink wheel can be described in non-words. It is black as the color, vinegar as the quenching, and between the operation, it is full of magic. In all industries, there is a place for it, and sincerity is a rare weapon.
