King Wen was very surprised and sent someone to ask him, "Are there many people cut off?" Why are you the only one so sad? " Bian He sighed, "I'm not sad because it was cut off, but because the precious stones were treated as stones, and the loyal ministers were treated as the ministers who bullied the monarch. It's sad that right and wrong are reversed! " Baoyu's title is stone, and Zhen Shiyin's name is Kuang, so I am sad. ) So, King Wen ordered people to cut this rough jade open, which was really rare. In order to reward Bian He's loyalty, Meiyu was named "He Shen Jade", which is the legendary He Shen Jade in later generations. Characterized by cyan, moist, shiny and moist. At first, it was about 15* 15*20CM, which was much smaller after being engraved into the national seal.
