Dou Niu plot
In the winter of 1940, farmer Niu Er is entrusted with the task of protecting his village's special Dutch dairy cow, which provides milk for wounded soldiers. Even when all the other villagers are slaughtered by enemy Japanese forces, Niu Er persists in protecting the cow. The loyal Niu Er outwits Japanese soldiers, starving refugees who abuse the cow's milk production, and greedy thugs who even try to slaughter the cow for meat! Due to their mutual struggle, the relationship between Niu Er and the cow becomes closer and closer and a lot of affection is created for each other.
