I heard that making a door depends on Feng Shui. I want to consult an expert. How about 2 meters *0.8 1 meter?

According to China's theory of Yin and Yang, odd numbers are Yang and even numbers are Yin, so the building dimensions of all houses must be odd numbers. In the past, the unit of measurement was size. Nowadays, the length of a building is usually measured in meters or centimeters. Generally, try to convert it into odd numbers. The old system and the new system should be unified as much as possible. Your door looks like a door. It used to be 1.9 m or 2. 1, converted into 5' 7 "or 6' 3". According to the current construction method, the width of the reserved hole is measured as 0.9 meters, which is converted into 2' 7 ",and then it is suggested that you convert the new system and the old system into singular numbers with reference to this meaning, or slightly change the new system or decimal number into singular numbers.
