Where should I hang the perpetual calendar in the room?

The clock is used to ward off evil spirits, as long as it is not hung on the door. Because it represents time and space, what the spiritual world fears most is to remind them of the existence of time. The clock should not be placed on any door, but in an open place, such as outside the window. Because the clock also has the function of ward off evil spirits, if there are evil spirits outside the window, you can also aim the clock at the side of evil spirits and resolve them under the condition of placing items.
