Lan Jinshu is the only descendant of Suzhou Lan's embroidery shop. His father Lan Jingxing is famous for his dragon and phoenix embroidery. His father was assassinated overnight, leaving only an unfinished dragon and phoenix cheongsam. Jinshu discovered that the cheongsam contained a code embroidered by his father with special silk thread, which pointed to the Beiyang government. A huge amount of military pay was lost; Duan Yichen, the marshal of the Duan family army, was ordered to trace the whereabouts of the military pay. He approached Jinshu in the name of customizing cheongsam; Japanese businessman Yamamoto Ichiro also sent spies to sneak into the embroidery village in an attempt to steal the cheongsam; revolutionary Shen Hanqiu was an old friend of his father, secretly protecting and guiding Jinshu ; Jin Shu gradually fell in love with Duan Yichen, but fell into conflict after learning his identity; she cooperated with Shen Hanqiu to crack the code and revealed that her father's death was related to the faction within the Duan family; Duan Yichen made a painful choice between family mission and personal emotions; the competition between various forces intensified , the embroidery village was attacked; Jinshu destroyed the cheongsam, but wrote down the password and made it public to prevent the warlords from monopolizing it; the old regime collapsed and a new order was established; Jinshu lost her lover, but kept the embroidery village and skills; she finally understood that the real inheritance is not wealth, but faith and love.
