With the rising living standards, China's food market has also experienced a consumption upgrade. Noticing Chinese people's great appetite for crayfish, Zhou and his team have introduced the method of rice-crayfish farming after years of field research. They help farmers raise crayfish in rice paddies, which can triple the income of farmers and enrich people's dining tables at the same time.

As for Zhou, despite tough working conditions, the research work has brought him a sense of happiness and fulfillment.

"It's nice just to be able to taste your own creation and know that what you have done will benefit more people in the future," says Zhou.

After a hard day of work, Zhou loves to take a walk in the fields, enjoying the peace and tranquility while watching the beautiful sunset.

That's the best reward for him.
