He also has a bigger goal - making everyone rich, or at least well-off. In 2018, the cooperative joined the poverty alleviation work that drove poor households out of poverty by transferring land and providing employment.

Over the years, the cooperative has also received free technical assistance from agricultural technicians at Baiyin Agricultural Science Institute, the seed administration bureau and the Baiyin district agriculture and shepherd bureau. The potatoes grown by the cooperative are large, smooth and well-shaped, low in water content, high in starch and tolerant of storage and lengthy transportation.

At present, the cooperative has transferred more than 60 hectares of land to 150 farming households and providing jobs for more than 20 poor households in the village. Each has achieved stability above the poverty line.

Now, Su wants to develop the business further. Since the cooperative became a provincial model agricultural cooperative and the original potato seeds it produced obtained the certification of pollution-free products in 2018, Su has more confidence.
