Song Wenxiu, a rural private teacher, calculates the future of his family and students with an abacus stained with corn paste. When the policy of "dismantling sites and merging schools" threatened the survival of the village small school, she and the villagers used the abacus as a weapon and the starlight in the soil as their faith to jointly protect this pure land of education. The core conflict focuses on the tear between survival and ideals - Song Wenxiu must not only struggle to pay for her daughter's medical expenses, but also fight against the erosion of rural education by corrupt official Ren Changsheng.
