Some friends know how to look at old scales.

There are two ropes, the black one in front seems to be one or two, so count down, and the yellow one in the back means kilograms.

The old scale, also known as the hand scale, was composed of a graduated wooden scale, a metal weight, a hanging rope and a weighing pan, which was mainly used for trading at that time. It is made according to the lever principle, which is convenient for people to buy and sell. It can be regarded as the quintessence of our Chinese nation and has a long history. Now it is collected in the Laolongmen Farmers Museum in Luoyang.
