Gentleman: Learning can not be done, green is taken from blue and blue is blue; ice, water is cold than water. The rope is straight in the middle of the wood, and the wheel is thought to be the wheel, and its curve is in the middle of the rules; although there are those who are violent and do not return to the pole, they are also allowed to do so. Therefore, the rope of the wood is straight, the gold is sharp, and the gentleman is erudite and the daily reference is self-conscious, then he knows and acts without fault.
Translation:
The gentleman said: Learning cannot be stopped. Indigo is extracted from bluegrass, but is darker than bluegrass; ice is made of water condensation, but it is colder than water. The wood is straight enough to conform to the straightened ink line, and it is made into a wheel by the process of casting, so that the curvature of the wood meets the standard of the circle. Even if it is dried up by the wind and the sun, the wood will no longer be straight, because it has been processed to make it like this. Therefore, the wood can be straightened by the amount of ink thread and then processed by the assistive device, the sword can become sharp after being sharpened on the whetstone, and the gentleman learns extensively and examines himself every day, then he will be wise and wise and there will be no fault in his behavior.
