Su Wanzhou, a child bride from a humble background, was bullied by her in-laws and was about to be sold. With her extraordinary pastry skills and meticulous scheming, she fought back, exposed her evil in-laws in public, and successfully earned her freedom. She started as a small vendor, using the exquisite pastry skills inherited from the imperial chefs of the previous dynasties, and worked step by step to create "Wanzhouji", the number one pastry brand in Beijing. During this period, she met Xiao Chen, a garrison soldier whose identity is a mystery and full of evil spirits. Xiao Chen was attracted by her tenacity and warmth and became her strongest support. As "The Story of the Wanzhou" rises in fame, Su Wanzhou not only has to deal with the malicious competition from her peers and the shameless entanglement of her ex-husband's family, but also inadvertently gets involved in the turbulent undercurrent of the court. It turns out that Xiao Chen is actually the God of War general who was unjustly exiled, holding a shocking secret that could overturn the world. Su Wanzhou used the intelligence network established by her pastry shops all over the capital and diners from all walks of life to help Xiao Chen collect evidence. After becoming successful and famous, the two of them chose to live in seclusion instead of being in love with power. They spread the "Evening Boat" all over the country and lived a life of fireworks in the world that they only envy mandarin ducks but not immortals.
