★The principle of Chinese steelyard is same as that of Balance. Chinese parents would face the baby with brush pen, the ear of corn, hammer and steelyard (separately stands for literature, agriculture, industry and business) on the first birthday. It is very auspicious if the baby grab steelyard. This foretells the child would be good at business in future. Actually Chinese steelyard is not accurate. Most could measure to 5 grams. But it is enough for selling vegetable. Therefore, it is still the retailer’ portable tool in vegetable market.
