As for the Tianyu Men's "Three Elements, Three Harmonies, Thirty-Six Dragon Seeking Compass," it's actually just a Feng Shui compass. Such a well-known Feng Shui tool doesn't need much introduction. In this long string of names, Tianyu Men represents the Ancient Xuanmen from Kunlun, the grandmaster of Feng Shui compasses. "Three Elements, Three Harmonies" refers to the regulations of the compass, and "Thirty-Six Dragon Seeking" specifically correlates to the divination book "Thirty-Six Dragons," making it a professional compass dedicated to seeking fortunes and opportunities.
Although it may seem to overlap in function with the diviner's compass, it actually complements it.
