In Chang'an during the prosperous Tang Dynasty, the willow color on Zhuque Street looked new every year, but it could not illuminate the difficult future of Liu Qing, a street painter. He fled from the south of the Yangtze River with his painting skills. He used the various scenes of the market as ink and the fireworks of Chang'an as paper. However, he was often ignored because of his unpopular painting style. Only Bingbing, a girl from the embroidery workshop, always accompanied him. She protected him from wind and rain with her gentle kindness, and ignited his undying enthusiasm with her firm trust.
A chance encounter by the Qujiang River, Liu Qing's paintings were unexpectedly appreciated by Princess Taiping, and she became a guest at the princess's palace from a street painter. Although the road to counterattack is flourishing, it also hides the jealousy and conspiracy of his peers and the love test of disparity in status - the frame-up of the painter Li De puts him in jail, and Bingbing's humble background creates a gap between the two. But in times of crisis, Bingbing used the tenacity and wisdom of an embroidered girl to collect evidence and clear his name. When he became famous, Liu Qing remained true to his original intention and promised that "Bingbing is the only one in this life."
From being dependent on each other in the woodshed to being in the painting workshop, from the dust in the market to the good stories of Chang'an, Liu Qing counterattacks life with her pen and ink, while Bing Bing sticks to love with tenderness. In the prosperity and turmoil of the Tang Dynasty, they illuminated the way forward with each other's glimmer of light, making a love that spanned classes and endured hardships as long as the willow color in Chang'an and as mellow as the smudge of ink, leaving a warm imprint in the memory of the thousand-year-old ancient capital.
