What's the difference between placing a square bronze tripod and a circle?

The bronze tripod in geomantic omen has the function of hiding wind and gathering gas, which is needed in geomantic omen, so the bronze tripod is very beneficial to people in geomantic omen. Because the bronze tripod can gather qi, Feng Shui pays attention to living in an angry environment, which can help people's physical and mental health and personality fortune. Of course, wealth includes more, including wealth. Ding can not only hide the wind and gather gas, but also ward off evil spirits. In ancient times, the tripod was a tool for holding objects during sacrifices, and later it gradually evolved into a function of regulating magnetic fields in geomantic omen. Therefore, ding has the function of hiding wind and gathering qi to ward off evil spirits, while ancient ding generally refers to bronze ding.
