In the late Yong Dynasty, when wars were frequent, Su Wantang, the daughter of the royal chef, was convicted of a crime for her mother, so she made a living selling snacks with her grandmother in Tangli Village, Jiangnan. The village was looted by the rebels and her grandmother died tragically. Wan Tang rescued the seriously injured Zhenbei General Shen Zhaoming during his escape. In order to repay her kindness, Shen Zhaoming took her to Kyoto. On the way, she met Chu Huaijin, a prince of the Wu clan who was feared by the royal family, and Xie Heng, a killer who was hunted by his enemies. Wan Tang, with his skills in medicated snacks and gentle and tough character, successively cured Shen Zhaoming's battlefield trauma, Chu Huaijin's cold syndrome, and Xie Heng's childhood shadow, and gradually became the "little sun" in the hearts of the three of them. As the situation in Dayong was turbulent, Wan Tang was involved in palace secrets and battlefield disputes. She conveyed warmth with delicious food and united people with sincerity. Finally, she and her partners quelled the war, gained family, friendship and love, and became the "Tangli girl" protected by everyone.
