In the ancient town of Jiangnan, the mortise and tenon joints are fragrant, and a journey of questioning about the persistence of craftsmanship and the deep love of the world begins.
Shen Yan, who had seen through the world and hid in the market, was tired of the glitz and disputes and kept his purity alone. However, when he met Su Wan, a sincere woman who worked hard for ancient mortise and tenon joints, she became emotionally involved and came to protect her. Su Wan devoted himself to saving the dying art of mortise and tenon jointing. Faced with technical difficulties, market temptation, human calculations and groundless criticism, he struggled but never gave up.
Shen Yan used his transparent wisdom as a lamp to help her break through obstacles and stick to her true heart; Su Wan used her pure original intention as a source of warmth to melt the loneliness in his heart and let him regain the fireworks in the world. The two work hand in hand to protect the craftsmanship and obsession of the old craftsman Li Shouyi, resist the impetuous pursuit of profit by capital, and expose the opportunistic conspiracy. In the fast-paced era, they stick to the roots of their craftsmanship and are determined to stay together.
After going through ups and downs and temptations along the way, they maintained the millennium foundation of the ancient method of tenon and tenon joints, and also maintained the deep love of not admiring glitz and having a sense of purpose. The long river surges, and I ask questions all my life, and finally understand: the craftsmanship is not let down, the true love never fades, and the heart has a destination, it is Changan every year.
