During the Warring States period, with the rise of seven powerful states and constant warfare, a jade artifact not only witnessed the rise and fall of nations but also, with its brilliant radiance, etched a poignant legend into the grand historical tapestry—the Heshibi. The most prominent chapter of this legend is undoubtedly the story of "Perfect Jade Returns to Zhao."

The story begins with the tragic tale of Bian He of Chu. Legend has it that Bian He, a man from Chu, discovered a raw jade stone in Mount Jing. He presented it to the Chu kings twice, only to have it mistaken for an ordinary stone, resulting in both his feet being amputated. It wasn't until King Wen of Chu ascended the throne that Bian He, weeping while holding the jade, prompted the king to order the stone to be cut open. Only then was the rare and exquisite jade revealed. With its warm luster and subtle glow, it was named "Heshibi" and became the treasured symbol of the Chu state, known throughout the land.

The allure of Heshibi lay not only in its unparalleled quality and craftsmanship but also in the cultural and political significance it carried. It was more than just a piece of jade; it was a symbol of royal power and an embodiment of national credibility. King Zhaoxiang of Qin, upon hearing of the Heshibi, coveted it greatly. He sent a letter to King Huiwen of Zhao, offering fifteen cities in exchange for the Heshibi. This was the origin of the "Perfect Jade Returns to Zhao" story.

Zhao, being weaker than Qin, found itself in a dilemma when faced with King Qin's threats and temptations. Refusing might provoke Qin to attack Zhao, while giving it up might lead to King Qin reneging on his promise, resulting in the loss of the precious jade for nothing. As the king and his ministers were at a loss, a retainer named Lin Xiangru stepped forward, volunteering to take the jade to Qin. He knew the journey was perilous but was resolute for the sake of his country.

Upon arriving in Qin, Lin Xiangru was received by King Zhaoxiang at Zhangtai Palace. The King took the Heshibi, admiring it immensely, but made no mention of the fifteen cities. Seeing this, Lin Xiangru devised a plan. He feigned that the Heshibi had a flaw, retrieved the jade from the King's hands, and then, with righteous indignation, declared to the King: "Your Majesty desires this jade, not merely for its beauty, but out of fear that our state of Zhao might not give it. Now that the jade is here, Your Majesty speaks not of the cities. I fear Your Majesty will break your promise, hence I have taken back the jade. If Your Majesty truly gives Zhao the fifteen cities, then I dare to present the jade. But now, since Your Majesty has no intention of compensating with cities, I request to return the perfect jade to Zhao!" Holding the jade, he leaned against a pillar, threatening to smash both the jade and his head if the King attempted to seize it. King Zhaoxiang, fearing the destruction of the jade and intimidated by Lin Xiangru's unwavering integrity, pretended to agree to fast for five days before holding a grand ceremony to exchange the cities.

Lin Xiangru, knowing King Qin's cunning, secretly sent a subordinate to flee with the jade under the cover of night, returning the Heshibi to Zhao. Five days later, King Qin discovered the Heshibi was gone and was furious but helpless. Lin Xiangru, facing the King's accusations, argued forcefully. His eloquent and impassioned speech ultimately compelled King Qin to allow him to return to his country. Thus, after many twists and turns, the Heshibi was finally returned perfectly to Zhao, and Lin Xiangru became famous throughout the land, being appointed as a high minister.

The story of "Perfect Jade Returns to Zhao" is not just a legend about a rare and precious jade; it is a symbol of the wisdom, courage, and integrity of the Chinese nation. Throughout history, the Heshibi was not merely material wealth but a spiritual totem. It bore witness to the intricate political struggles between the various states during the Spring and Autumn and Warring States periods, and it reflected the noble integrity of the scholar-official class who dedicated themselves to their country. Lin Xiangru's resourcefulness and courage, his defiance of tyranny, demonstrated the powerful spiritual strength that the Chinese nation could unleash in times of crisis.

To this day, the whereabouts of the Heshibi remain a mystery, but the story of "Perfect Jade Returns to Zhao" continues to shine brightly across millennia. It is not just an anecdote in history textbooks but a deeply ingrained cultural symbol. It reminds us of the importance of upholding principles and integrity when faced with temptation and power; it also encourages us to dare to fight and to use wisdom in adversity. The cultural heritage embedded in this jade has long surpassed its intrinsic value, becoming an eternal pearl in the treasure trove of Chinese civilization, continuing to enlighten future generations and perpetuate the national spirit.
