The idiom "He Shi's Jade, Sui Hou's Pearl" originates from two ancient Chinese legends.

The first tells of Bian He, a man from the Spring and Autumn Period. He found a piece of unpolished jade and presented it to King Li of Chu. The king's jewelers declared it a mere stone, and Bian He had his left foot cut off as punishment. Later, he presented it to King Wu of Chu, who also believed it was worthless, resulting in Bian He losing his right foot.

It was not until King Wen ascended the throne that the jade's true brilliance was recognized, and it was named "He Shi Bi" (He Shi's Jade), becoming one of the most famous and precious jades in Chinese history.

The second story involves Sui Hou, a marquis during the Zhou Dynasty. He once rescued a wounded snake. To express its gratitude, the snake spat out a magnificent, luminous pearl, which became known as "Sui Zhu" (Sui Hou's Pearl).

Both "He Shi Bi" and "Sui Zhu" symbolize objects of extraordinary value and rarity.
