A pulley is a lifting device for extracting well water.

A derrick is erected on the well, and a shaft that can be rotated by a handle is installed. A rope is wound around the shaft, and one end of the rope is tied to a bucket.

Shake the handle to drop the bucket together to extract the well water.

The original version of the Duke of Zhou interprets his dream: Dream pulley.

This is also conducive to the dream of immersing yourself in the countryside.

Kings dream of this, it is a sign of repeated losses and repeated recovery, and the sign lies in the harem; You dream of this, and if you have any recovery, the luck lies in your wives and concubines; Scholars and common people dream of this, and the beauty is better than that of others; The poor and humble dream of this, and it will be given to you in the morning and at night. It is unclear and without regrets.
