Lian Po
The "Shiji" "Biographies of Lian Po and Lin Xiangru" section records a famous story. In 283 BCE, King Zhaoxiang of Qin (r. 306-251 BCE) schemed to obtain Mr. He's "bi" disk – this is the first recorded usage of modern term "Heshibi" 和氏璧 without classical "zhi" 之—from King Huiwen of Zhao (r. 298-266 BCE) – and deceitfully offered to trade away a large portion of Qin territory for the jade. However, when Xiangru discovered that Zhaoxiang never intended to give away Qin land, he tricked the king and managed to return the jade-disk back to Zhao.
