2 . Do you like potato chips? Can you imagine someone postponing graduation just to make them? This is exactly what happened with Du Haotian, a graduate student from Shaanxi province.

The potato chips Du is making are called guoba, originally made of millet rice, but here Du chose colored potatoes as the ingredients.

Zhenba County, located in the southern part of Shaanxi, has been striving to promote high-quality potato sales, despite the inconvenient geographical conditions. Du Haotian, a graduate student of Northwest Agriculture and Forestry University, together with his team, introduced NWAFU’s colorful potato to solve the problem. After adjusting the recipe several times, it gradually turned into a popular snack at Du’s university. “We sold 10,000 yuan (of chips) in an hour during the trial period,” Du said.

At the end of last year, Du’s team set up their own factory in the village to commercialize the colorful potato and derivative snacks, planting and producing the products locally. At the beginning of this year, the production line was officially put into operation. It can process 5,000 tons of potato snacks per year, increasing the added value by 1,000 yuan to 1,500 yuan per ton of potatoes. However, while helping the local community, Du Haotian is under pressure to graduate.

Although he was supposed to graduate in June 2020, Du applied for a postponement for one year. Du said the production line project is still under construction and he wants to live up to the expectations of the villagers. “A lot of my friends and teachers told me not to do that, but I still want to stay and support the village for another half year. Otherwise, if the factory is built but does not work out, then it would be against my original intention.” Eventually, Du’s mentor supported him. Once, a villager recommended the potato snack to Du before realizing he was the founder. “At that time it warmed my heart and I experienced a sense of recognition.” Recently, Du’s potato snacks took part in a college food competition on behalf of his university. His product once soared to the top of the list with the support of many local villagers, which touched Du.
