Why put green onions on the beams?

It has something to do with feng shui. In our traditional numerology divination theory, whether it is the financial officer in the eight characters or the "turtle's back is expensive" in face divination, there is a simple truth: only when people carry a load can they go far and achieve great success. Slowly, this numerology concept of "those who bear the burden are expensive" has also penetrated into the minds of the people, thus having a positive impact on Feng Shui and architecture. When building a house, putting money on the beams is an intuitive expression of the house built, or that the family can "bear the money", which is a good blessing for prosperity. At the same time, putting money on the beams has another meaning: simple ideas to avoid being stolen at home. In the history of human currency, gold and silver currency occupied a very long historical period. As far as China is concerned, it was not until the Song Dynasty that paper money: Jiaozi appeared. There is an obvious disadvantage in the use of gold and silver metal currency: it is inconvenient to carry, easy to be found and easy to be stolen. In this way, the storage of money has become a very important issue, so some people choose to put their belongings on the beams, which can reduce the risk of theft. Slowly, this folk tradition also affected the construction of Feng Shui. When building a house, people want to put a copper coin on the beam to symbolize the safety of property at home and not provoke foreign thieves.
