Chang'an Is Covered with Snow, and Old Friends Are Nowhere to Be Seen.

Everyone in Chang'an City knew that Xie Linchuan, the eldest son of the Zhenbei Hou Mansion, had fallen in love with Shen Zhiyi, an orphan from a poor family when he was young. He rebelled against his family for her, knelt down and begged for marriage for her, and promised her that he would live up to his promise for the rest of his life. But later, it was she who wrote an unfeeling letter that cut off his thoughts and forced him to deliberately defeat him at the border, almost destroying his pride for half his life. He hated her for being ruthless, hated her for betrayal, and hated her for turning around most decisively when he needed her most. So he married someone else, became a highly respected minister, and never looked back. It wasn't until many years later that he knew—— It turns out that she had sacrificed her life for that love letter back then. It turned out that she was suffering from a disease and had already run out of energy, but she still managed to survive the last snow for him before she died. It turns out that he hated her for half his life, but she loved him for her whole life. On the third day after her death, the truth came out. Overnight, the arrogant Mr. Xie turned his head white. But the snow in Chang'an remains the same year after year, and the person he wants to wait for will never come back. "The most painful thing in the world is never separation, but when you finally know how much she loves you, she is no longer here."
