Poems about rulers

The ruler is short, the inch is long, the things are insufficient, the wisdom is unclear, the numbers are not grasped, and the mind is not clear.

It is placed under the front window. The left hand holds the knife ruler.

One foot of cloth can be sewn. A bushel of millet can still be pounded.

The jewels are not treasures, but the rulers and tablets are treasures.

The clothes worker holds a knife and a ruler, but he abandons me as if he has left me behind.
