I bought a stone scraping board on Taobao and spent 40 yuan. It belongs to Hengshui, Hebei. Is it true or not?

I work for April Peninsula Company. The company sells Bian Shi, called April Bian Shi. When I saw the answer, it was quite unprofessional. I couldn't help coming in and saying a few words. Bian Shi's finished products are all black. The so-called red and yellow substance, the scientific name stone embryo, is the original stone that has been weathered and not polished for thousands of years. Please don't give any misunderstanding. However, one sentence is right. The real bian stone can't be bought for 40 yuan. Bianshi is the most delicate clay crystal structure, which is produced at the top of the round mountain in the ancient Sishui River Basin, and is unique to China, with very little existence. You'd better ask for the test report before buying bian stone, because some stones are radioactive and will cause a burden to your body.
