First of all, you can't cross the hall. This clock looks at feng shui. There are two situations:
One is the gossip feng shui clock, which says it can be changed. But I think its function is not as exaggerated as what outsiders say now. In fact, the function of that thing may not even be comparable to an ordinary gossip mirror or magic.
One is our common bell, which can ring the time at a specific time. This kind of clock will give out the sound of metal collision, which is usually used to dissolve the Erhei/Huang Wu Qi in geomantic omen. So the general placement position is also the position of Erhei and Huang Wu in the room, which is legally determined by the mysterious void. The reason is to use the vibration caused by the metal sound of the bell (so its sound is golden) to vent the soil where the two black and five yellow flying stars are located in the house (two black and five yellow behavior soil)!
You can hang this clock on the non-main wall.
