Cover the quilt in summer and snowflakes flutter in October. In the production area of chicken blood stone, there are many legends about chicken blood stone, one of which is the phoenix locust, and the blood is sprinkled on the Jade Rock Mountain.
Legend has it that in ancient times, when a pair of beautiful phoenixes soared in the heavenly court, they heard the sound of mourning from time to time, looked down, and saw that locusts were plagued, plagues were prevalent, crops were not long, their eyes were desolate, and the people were miserable. Seeing this, the good and righteous phoenix decided to use his own strength to eliminate the locust plague, disperse the plague, and help the living beings. Through hard work, the good wishes were fulfilled, and the grateful people asked the phoenix to stay and bathe in morning songs and twilight songs together. The phoenix was touched by the sincerity of the people, and built a phoenix swamp on the top of a mountain - Kangshan Ridge, and soon around the phoenix swamp, all the mountain rocks became white and transparent, like white jade, and the jade rock mountain got its name. Hundreds of birds on Yuyan Mountain sing in unison, and the people under Yuyan Mountain live and work in peace and contentment. But at this moment, a pair of strong birds and lions came from the mountain, and they saw that the phoenix nest lived on such a beautiful mountain, creating such a brilliant performance, and they were jealous of the people's favor, so they decided to drive the phoenix away and occupy the phoenix swamp. One day, just as the female phoenix entered the incubation period, the male phoenix went out to forage, sneaked into the phoenix's nest, attacked the female phoenix, the female phoenix bravely fought with it, and the battle of the phoenix and lion made the wind on Yuyan Mountain sound and the sun and moon were dark. When the male phoenix returned to the nest, the female phoenix was pecked by the bird lion and broke a leg, and the blood spilled on the jade rock mountain, and finally, the phoenix defeated the bird lion with sadness and anger by its own wisdom and strength, and tearfully buried the phoenix egg that had been innocently trampled and flew away.
When the phoenix departed, the people mourned greatly, and they prayed to heaven and asked the gods to bless the righteous phoenix. The sincerity of the people, the cry of the phoenix, touched the heavens and the earth. The Jade Emperor sent the crown prince Xia Fan to inspect the facts, and ordered Jizo Bodhisattva to turn the phoenix blood and phoenix eggs into beautiful Danshi, and gave the Danshi the power to turn each danshi into a fierce ji, drive away evil and promote good, and punish evil and love. Since then, the phoenix blood and phoenix eggs on Yuyan Mountain have been buried for thousands of years, and have become today's rare and precious - chicken blood stone, chicken blood stone should have been called phoenix blood stone, which is the color found by later generations when mining and the freshly slaughtered chicken blood droplets on the jade, before the habit of calling it "chicken blood stone".
Quality discernment
Tasting chicken blood stone, first of all, is the red color of "blood", which is better for its freshness, coagulation and thickness.

Using a better texture of the Chang fossil stamp, select several of its eye-catching places, dig out a small pit of different shades, and then embed it with red mercury sulfide paint, and then polish it after its natural shade is dried, and then polished and waxed. Because the embedded chicken blood (mercury sulfide) has no layers, and the junction between the blood and the Chang fossil is hard in color and there is no transition.
Second, the impregnation method
Take a Fangchang fossil, coat the place where it is needed, dry it and then apply it, then shade it, so that its blood is slightly layered, and then put it in a transparent resin to impregnate it, so that the whole body is immersed, pick it up and dry it, and then use fine water sand to light it, that is. This method is due to the resin is easy to age, the skin will be yellowed over time, and the internal stone color is not in harmony, while the pores of the resin skin are relatively thick, with a magnifying glass to carefully observe its surface has a little bit of small brown eyes, and all this is really Changhua chicken blood stone does not have
