Don't play too fast when playing jade, the temperature is too high. Because Calligonum yuhua, one of the seven treasures of Buddhism, has been growing in the ocean at low temperature. Therefore, the speed should not be too fast, and the temperature should not be too high, otherwise the wheel lines of jade-like tortoise shells will quickly surface due to water loss, that is, cracks commonly known as cracks will appear, which will affect the appearance.
Don't use ice water to stimulate when playing jade. When the temperature of jadeite is close to the hand temperature, it can be washed with cold water to reduce the temperature and continue to play! Don't use biting cold water, ice water, or throw it directly into the refrigerator. Excessive temperature difference may cause jade to burst, even a perfect product without moth and crack may burst.
When playing with jade, don't throw it into boiling water to cook. Calligonum emeraldum is most afraid of the environment with large cold-heat ratio. Because it is an organic gem with high calcium carbonate content, Calligonum Emerald has low toughness and different internal texture coefficient. Once it encounters a high temperature environment, it is easy to break.
5. When playing with jade, don't be a tea pet. Many scholars who play with jade have the habit of soaking and cleaning jade with boiling water, and some people like to pour the remaining tea on jade, which is called tea pet warming jade. However, this method is completely unsuitable for Calligonum yuhua! Especially hot tea, as long as the water temperature is above 80 degrees, 1-2 seconds, there is a great chance that it will be broken (not excluding a small number of heat-resistant cockroaches).
6. Don't touch strong acid and alkali when playing with jade. In addition to the environment with high water temperature, Calligonum yuhua is also afraid of the environment with strong acid and alkali. Once it comes into contact, it will be prone to atomization, so you must pay attention to maintenance when playing Calligonum yuhua.

Maintenance and use of dragonflies
1. In order to avoid external pollution, the surface is waxed and worn for about a week, and the wax will automatically separate and return to its original state. After wax separation, the gold wire will automatically generate negative ion replacement to realize the existing function.
As gold wire and pearls are organic gems, they should not be exposed to acid or alkali. If they come into contact with sweat or dust, please rinse them with clean water and dry them with a fine cloth.
3. Don't wear it when taking a shower or doing housework, and don't collide with other metal ornaments. Wipe and maintain with natural sheep oil (natural pure sandalwood oil can also be used) baby oil or neutral emulsion every month.
