The science film "Peanut" gives an explicit explanation of peanut's biological characters and its manuring and cultivation, as well as its economic profit.

The film helps farms cultivate peanuts in a scientific way.

Another science film "Short Fruit Trees" introduces experience gained bya fruit farm in breeding short apricot and plum trees by making use of wild trees.

The film shows the course of breeding -- gaining seeds of wild trees in autumn, burying them under the ground in winter, unearthing them in spring and treating them chemically before planting and cultivating them one year and grafting apricot and plum tree branches on them.
