The scale is a weighing tool that has been invented on the basis of the principle of leverage and has become widely used after the qin dynasty has been unified. The initial wood scales were crude and inexact, and went to tang dynasty for improvement, stating that there were more precise units of measurement such as money, points, calibration, etc., and redefinition of metrics. As a result of the change of time, the metrics were changed until the 1980s, when they were directly harmonized with international standards and were based on kg, ending its glorious history.

In the 1960s and 1970s, manual scales were replaced by electronic scales that became increasingly popular, with only isolated rural areas retaining the habit of manual scales, and few now understand the labels on the pole, representing a few pounds. The historical manual claims thus exited the life stage, and in another form the value of the collection appeared. (charts are the tools needed to make scales)
Manual scales have three types, which can be divided into large, medium and small, depending on the length of the said pole and the weight of the scales. Large sizes can be called 150 kg and small sizes can be accurate enough to capture chinese medicine for chinese pharmacies. (chart to knock on the tail to match it)
The production of manual scales is hand-held from the selection material to the measurement scale, and measurement of scale is important, and the weigher must have fair scales. In the heart, one cannot make a weight less than a vacancy. (chart marks the scale of the scales)
The scale is the most complex process, and it will be pierced at the scale of the scale, but it will not be able to pierce it, and as long as one wears it, it will be rendered useless. In general, the 15-kilogram scale is 300 scales。
They enter the hole with a thread of aluminium, and they flatten and break with a sharpening knife. It is thus clearly marked at the scale of the scales, which makes it easier to see. In general, this step allows artisans to identify whether they did it themselves and can be considered a security mark。
In the end, the fine scales are sharpened according to requirements and preferences. A hand-made scale has brought together the wisdom of the ancients and, although it has been replaced by electronic scales, the “fairness and fairness” it represents also continues。
