On the principle of a technique
There is a technique called Formalin-ethyl Acetate Concentration Technique. Its principle is profound, it is related to the gathering and dispersing of things, the mystery of the law, and it has special power in all things.

The principle of this technique is first in the nature of Formalin and ethyl Acetate. Formalin has the ability to solidify the shape, which can make the structure stable when encountering objects, just like the support of beams and columns, so that the shape and quality of things will not dissipate. Ethyl Acetate has the effect of dredging, which can hinder the flow of stagnation, the flow of materials, and the diversion flow of the river canal.

The two are used in combination and complement each other. First use Formalin to solidify its essence, so that the foundation of things can be solid; then use ethyl Acetate to ventilate its qi and promote its subtle convergence. In this way, things can be gathered in one place to achieve a change in concentration. It is like gathering a crowd to form a source, and combining the forces of the crowd to achieve great things.

The application of this technique is beneficial to all karma. Or it is used for the analysis of micro-matter, so that the hidden are revealed; or it is used for the extraction of materials, so that the fine are gathered. If the principle is clear, and the law is used well, then things will be successful, and the work will be achieved. In the progress of the art, it is the key method.
