What are the feng shui stresses on the placement of office desktop items?

Feng Shui for desk items:

From the perspective of Feng Shui, first of all, the computer should be placed on the left side, while some work-related items, such as documents and the like, can be placed on the right side, but they should be placed neatly, preferably in file baskets or file boxes, and files that have not been used for a long time should be placed in the office cabinet. The office cabinet can be placed at the inner position under the desk, that is, at the lower right. Generally, desk calendars, pen containers, telephones, etc. can be placed on the desk, and things unrelated to work, such as snacks and popular magazines, should be avoided. If you leave your seat for a long time, you should sort out the documents on your desk and put the chair in the right position.
