For example, the depth of the space in the hanging closet should be greater than or equal to 530mm, the distance between the upper edge of the hanging stick and the upper surface of the hanging long coat should be greater than or equal to 1400mm, the height of the table furniture should be 680mm~760mm, and the middle drawer of the desk. The middle clearance height from the lower edge to the ground height shall be greater than or equal to 580mm, and the clearance height between the bookcase layers shall be greater than or equal to 230mm~310mm. If the furniture is smaller than the specified size, it will cause a lot of inconvenience and affect the use.
