What's the difference between a three-point compass and a three-point compass?

(1) The key difference is that the Trinity is about the Trinity of Heaven, Earth and Man. They are all based on the trinity of heaven, earth and people, and the site is vertical, with sand removed from the sky plate and water connected to the people plate, which is 7.5 degrees different from the site. It was invented by Yang Junsong.

(2) Taking the three elements as an example, if three elements and nine elements are used to regulate qi, the division of Yin and Yang is also different from the triad, that is, the three Yin San Yang alternate with each other in position, which is different from the triad, and there are generally no two sets of heaven and man.

(3) In addition, there may be a substitute layer in the triple disc. And there is a comprehensive plate, which is a three-in-one system.

(1) ternary disk is also called Pan Jiang or Pan Yi. It is said that the Yi Gua layer was created by Mr. Jiang Dahong, a geomancer in Qing Dynasty. The main feature of ternary disk is that there are sixty-four hexagrams, generally there is only one layer in twenty-four directions, that is, the position is a needle, which can be used to calculate the good or bad of its position.

(2) The main feature of the Trinity Disc is that it is composed of three layers and twenty-four directions, namely, there are three circles of site needle, middleman needle and ceiling needle, which are used together with the contents of other circles to orient, expel sand and absorb water. Three-in-one disc is also called disc, and the compass made in Huangshan City is called "emblem disc" in history, all of which are made by hand with natural materials.
