Bloodstone should be avoided being placed in the sun or under the lamp for a long time, so as not to reduce the value of chicken blood because the red part darkens. Usually, it should be rubbed or soaked in good lubricating oil, such as jade, to isolate the stone from the air, reduce the possibility of temperature difference cracking and increase the warmth of the stone. In addition, collision and breakage can be avoided.

Proper playing and rubbing of bloodstone can make it look "old light", which is also commonly known as "treasure light" and become "old stone" more pleasing to the eye. The reason is exactly the same as that in Pan Yu. However, Yin Shi or sculptures engraved with thin ideas should be avoided, so as not to destroy the sculptor and make him unrecognizable.

For the uncut Yin Shi, or the original stone, you may wish to rub it more; The uncut Yin Shi has the advantage of not being damaged easily. Playing with stones and raising stones is fun, and it is difficult to enter its territory without personal experience!
