wuren is a kind of stuffing for traditional Chinese cakes (such as moon cakes). It is made by frying five kinds of materials, namely walnut kernel, almond, peanut kernel, melon seed kernel and sesame seed, peeling and crushing, and finally adding white sugar. In ancient China, there were five moral principles of "benevolence, righteousness, propriety, wisdom and faithfulness", and "five benevolence" was just a homonym.

The raw materials for making Wuren moon cakes are: standard flour, fine sugar, cooked vegetable oil, lard, eggs, rose sugar, syrup, cooked standard flour, walnut kernels, peanuts, pine nuts, hemp seeds, washed sesame seeds, preserved wax gourd, white wine, alkali and orange peel sugar. South almond, melon seed, olive seed, sugar orange cake and cooked glutinous rice flour (replaced by cooked flour) in the traditional formula were removed, and the consumption of preserved wax gourd was increased.

The production process includes syrup preparation, dough making, stuffing making, stuffing forming, tray baking, cooling and boxing, which is the finished product.
