Summary of Yu Yu Xi Yu Six

"There is a heart for beauty," and our ancestors have always loved jade. Appreciating jade is a noble hobby. Our ancestors recognized the hardness and beauty of jade as early as 5,000 BC. Jade can not only be used to grind tools, weapons, but also beautiful decorative objects, bearing people's artistic feelings and spiritual pursuits, and It is also used as a ritual to sacrifice ancestors. Therefore, at the beginning of Chinese jade, it has a mysterious color and evil spirits, which symbolizes the role of power, wealth, and nobles.

During the Spring and Autumn Period and the Warring States Period, Hetian jade was heavily input into the Central Plains. The royal princes competed with Hetian jade. The jade lamp of the Forbidden City collection is the standard Hetian jade. At this time, the Confucian scholars combined the ritual study with Hetian jade and used Hetian jade to reflect Etiquette thinking. In order to adapt to the ruler's love of Hetian jade, the Confucian traditions of benevolence, wisdom, righteousness, courtesy, music, loyalty, faith, heaven, earth, and morality are attached to the various physical and chemical properties of Hetian jade. Following the "gentleman is better than the jade", the doctrines of jade, five virtues, nine virtues, and eleven virtues came into being.

With the approaching of the 2008 Beijing Olympic Games, Hetian jade, which is the raw material for the emblem of the Beijing Olympic Games, has attracted more and more attention from collectors and ordinary people. The whole country has raised the upsurge of Hetian jade collection. As an ordinary people and a junior Tibetan jade, collect a good jade and learn to maintain it. The six outlines are as follows:

1. Do not hit hard objects. The jade is easily broken after being hit. Sometimes the naked eye does not see cracks, but the molecular structure in the jade surface has been damaged, resulting in dark cracks, which will appear for a long time, greatly impairing its perfection and collection value.

2. Avoid dust and oil as much as possible. If there is dust on the surface of the jade, it should be cleaned with a soft brush; if dirt or oil stains are attached to the jade surface, it can be washed with warm soapy water and then washed with water. Never use chemical degreasers. For the heavily contaminated old jade, professional companies that produce and clean jade can use professional ultrasonic cleaning and maintenance.

3, jade pendants should be placed when not in use, it is best to put them in jewelry bags or jewelry boxes to avoid bruises.

4. Avoid contact with perfume, chemicals, soap or human sweat. Because the jade is exposed to too much sweat, it will be eroded and the outer layer will be damaged, affecting the original vividness. In particular, white jade-leather white jade is more resistant to sweat and oil. After wearing it, wipe it with a soft cloth.

5, do not set the sun for long-term direct. The jade sun exposure is experiencing thermal expansion, and the molecular volume increases, which will affect the jade quality. Therefore, it is more likely to be close to the heat source.

6, too dry environment is easy to evaporate water, thereby damaging the quality of jade.

In today's time-changing landscape, the special and unique qualities of jade have long been rooted in the hearts of Chinese Chongyu and Aiyu. Jade represents beauty, dignity, perseverance and immortality. "Humble and gentleman, Wenrun Ruyu", while possessing jade, also cultivated his own sentiments and deepened his own soul.
