What are the feng shui taboos for placing clocks and watches in restaurants?

The dining room clock should not be inward, and it is best to face the door or balcony. Because when there is no one in the room, the air is still, and the swing of the wall clock can make the air move and make the room full of vitality. But the wall clock can't be hung in the middle of the hall opposite the door. Because "clock" and "end" are homophonic, if someone opens the door and comes in, they will look up and see the clock (end), which may be associated with bad luck.
