After dancing in the square, Li Dazui heard that his granddaughter Zhang Xiaoyan was missing. As the granddaughter of a 14-year-old mentally retarded child, she has been repeating grades and is still in the fifth grade of elementary school. She usually has no grudges against anyone, so who will be kidnapped?
So she, who usually loves reading detective novels, helped the police find her missing granddaughter. Who knows...
The inspiration comes from the secret room murder case in the granary in the 1960s and the TV series "Sister Ma".
Concept: Square dancing aunts also have life value
