Guzheng is a wood with a loud voice and gold on it. No matter where it is placed, it will be prosperous if all evils are eliminated and peace is guaranteed.
Lack of soil and fear of fire are the shortcomings of guzheng.
When playing the piano, it is easy to "spend money" near the doors and windows, and stay away from the stoves for heating and cooking to avoid the safety hazards caused by "fire".
Everything else is fine.
