Blowing Principle
The principle of bleachings was to make objects lose their color through the oxidisation properties of bleaches. Different types of bleaches had different principles. The principle of the bleaching-powder was that the bleaching-powder would produce hypochloric acid when it came into contact with water. The hypochloric acid could catalyze the coloring matter, thus achieving the purpose of the bleaching-powder. The principle of hydrogen dioxide was that hydrogen dioxide was a strong oxidiser. It could destroy the " chromophore " inside the organic color substance and cause it to lose its original color. The principle of the absorption bleachings was that the substance had a large surface area, which could absorb the dye and make the substance fade. Other bleaches such as sulfur dioxide and ClO2 had similar principles. In general, bleaches change the color of objects or fade them through an oxidization reaction.

Reflex principle
The principle of reflexivity was proposed by Soros. This principle was based on a phenomenon that existed in human affairs: when someone was involved in something, the participant's view of the world was one-sided and distorted (fallibility principle), and these distorted views would in turn affect the things related to the point of view.
From the perspective of the connection between the participant's thinking and the situation they participated in, it could be decomposed into a cognitive function and a participation function. In the cognitive function, the participant's cognition depends on the situation; in the participation function, the situation is affected by the participant's cognition. The interaction between the two is called reflexivity, which can be expressed as a pair of recursion functions: y = f(x), x = q(y).
In the field of economics, traditional theories often avoided or denied reflexivity, and Soros believed that a fundamental factor in the existence of reflexivity was human cognitive bias. In addition, Kant believed that the application of moral laws in practice was based on the principle of reflexivity. This principle meant that every moral law must become a basic principle, and every rule must conform to the basic principles that any rational person could accept. In the moral theory he constructed, he emphasized human free will and free decision. This principle was widely used in modern philosophy and promoted the development and progress of human thinking.

The Principle of Musket
The musket was mainly composed of two parts, the musket tube and the musket holder. The principle was that through the slender barrel and smaller caliber, the gas pressure produced by the explosion of gunpowder in the barrel was greater, so that the projectile could obtain more energy. When making a musket, the making of the musket tube was the key. The craftsman would roll the fine iron into two iron tubes, one big and one small, and make them close together. Then, he would drill them into a musket tube with smooth inner walls and uniform thickness. When the musket was fired, the energy produced by the gunpowder explosion pushed the bullet out to achieve the purpose of shooting.
