From the five elements, the piano belongs to gold. If you need gold for your eight characters and five elements, then learning the piano will definitely help you.
One more thing, if you buy a second-hand piano, you'd better put it in the sun for a while! This approach can offset the influence of the last person from the perspective of eight-character feng shui. Because the last person who uses this piano for a long time will produce a magnetic field in that place. Put this magnetic field in the sun and you can cancel it!
One more thing, if you put the piano in the right place at home, you can remove the role of urging money and change the role of suffocating.
