We often say that "the more you look at a beautiful woman in the light, the more energetic she is", which means the same thing, because the hazy effect of the light will make our vision more illusory, thus creating an illusion of "the more you look at it, the more beautiful it is".
China people have a special love for "beautiful jade", which is not found in other parts of the world. On the one hand, jade has a good moral. Since ancient times, China literati have had the habit of wearing jade, and there is a saying that "a gentleman wears jade and jade never leaves his hand".
Jade was considered spiritual by the ancients because of its pure and flawless characteristics. Moreover, the ancients believed that jade is the product of the aura of heaven and earth, which has the significance of exorcising evil spirits and avoiding disasters. Wearing it often will make jade more rounded.
The quality of jade has a very special appraisal standard, which is called "water head". We often say that this jade is "full of water", that is to say, this jade has a good texture, and the polished jade is top grade in luster and texture.
If you put this so-called "water head" under the lamp, it will make the luster look purer and more oily. This affects the original true brightness of jade, which is also the experience summarized by ancient people in long-term exploration, and it can be regarded as providing a doorway for future generations.
However, with the development of modern science and technology, experts have begun to identify the quality of jade and issue identification certificates. We ordinary people look at jade, as long as the color likes it, there is nothing to struggle with.
