Li Weiguo accidentally traveled to a courtyard in 1962 and became a family member of a martyr whose parents "sacrificed". Faced with the plight of lack of food and clothing and the covetousness of neighbors in the courtyard, he accidentally activated Pinduoduo's golden finger and was able to purchase supplies from modern times. With this secret weapon and the care of his father's old comrade Yang, Director Yang, he grew up in a low-key manner in a special era. While dealing with the sophistication of people in the courtyard, he used modern materials to improve his life, and lived his own wonderful life step by step.
