Su Weiyu, a daughter of an aristocratic family, lost her home due to a late-night disaster, and followed her father's last wish to travel around the world with the dagger "Tingxue". When she was new to the world, she met Lin Qingyan, the young master of the Qingfeng Sword Sect, by chance at the Dufeng Bridge in Suzhou. The two became friends by accident and went south together to watch the tide in Qiantang.
She was once a lady who recited poems and wrote poems in a deep house, but now she had to learn to protect herself in a strange world; he was a daughter of a famous family, traveling around with a heart of experience, but he was willing to provide shelter for her who met by chance. Along the way to the south of the Yangtze River, there are not only the fireworks of Suzhou City, the sweet drunken crabs of Zuixian Tower, but also the undercurrents of the rivers and lakes - the secret that my father guarded before his death, and the past behind the "Tingxue" sword are gradually emerging as the two of them move forward.
A youthful friendship that supports each other in the wind and rain, when bookishness meets the smell of rivers and lakes, when the pain of the past meets the glimmer of progress, Su Weiyu will eventually lose her youthfulness in the stumbling, hold the "Tingxue" sword in hand, and find her own place in the vast rivers and lakes.
