How many meters should I leave in front of the motorcycle room?

In Feng Shui, there is no absolute requirement for the size of the doorway.

Generally speaking, the door of a house is bigger and the door of a house is smaller. But the 3.4-meter door seems a little big. Besides the subjective moderate size, Feng Shui also has some things related to the size of doorways. Most importantly, the porch is the air inlet of a house. If it is too small, you won't get much gas. If it is too big, you may not get special gas, because if it is too big, it will exceed the span of a hexagram or a mountain, and the gas collected will not be rich and miscellaneous. Within a certain reasonable range, the exact length and width of the door can also be determined according to the good or bad luck of Lu half a foot, and the size of the inner frame after the door is completed shall prevail.
