On the New Year's Eve of the Year of the Horse, the fairyland of New Year customs is on the verge of collapse due to the indifference of the human world. The last guardian god Sheep is strong and has become the last hope of the fairyland. This generally recognized good-for-nothing god has little magic power and writes anti-blessing characters on a daily basis. His only specialty is making woolen spring rolls that sometimes work but not always work. However, the Kitchen God entrusted him with a blank New Year picture scroll and ordered him to find the true meaning of the New Year before the fifteenth day of the first lunar month of the Year of the Sheep in Dingwei. Otherwise, the fairyland and the memory of the New Year will be permanently lost.
By some strange combination of circumstances, the strong-willed sheep descended to earth and actually possessed the mutton sheep "Maomao" and became the signature of restaurant owner Lao Hao's New Year's Eve all-sheep banquet. There were only 30 days left before being cooked, and 99% of the mana was still sealed. In a desperate situation, he met Nuan Nuan, an 8-year-old girl who longed for the traditional taste of the New Year. Since then, he has formed a bond and become each other's guardians.
In order to save his life and complete his mission, Yang Jianqiang unlocks the warmth of the world in a clumsy way: he uses wool dumplings to awaken Grandma Chen's rice cake making skills, builds up the neighborhood friendship of the elderly living alone, and resolves neighborhood conflicts; on the night of the power outage, he uses up his remaining power to let community residents put aside their barriers and regain memories of the New Year with hand shadow stories in the dark.
On New Year's Eve, the butcher's knife is coming, and Nuan Nuan fights to the death with her childlike body, while Yang Jianqiang also exerts his divine power to show his holiness, reminding everyone that the taste of the New Year is not about killing and extravagant feasting, but about the warmth and protection hidden in the fireworks. In the end, the warmth of the world in the Chunhuili community gathered into light, lighting up the scrolls of the New Year paintings, and painted a new scene of "fireworks in the world, and the lanterns in the heart are always bright", and the fairyland was reshaped. Yang Jianqiang also grew from a useless person who evaded his mission to a real guardian angel who takes root in the world and protects daily warmth. He stays by Nuannuan's side and guards the good times of the world year after year.
