How much air can float out from the second floor of a house built in Zhoushan?

1.5 to 2 meters. Most people will choose to float out by 1.5 meters. It is best not to exceed 2 meters, otherwise the deflection will be relatively large. Nowadays, many self-built houses in rural areas have limited area on the first floor. Many people build the second and third floors in a floating-out style, resulting in a top-heavy appearance. This is called a disordered layout in Feng Shui.
