"When my grandson grows up, I will send him to join Wang and his team."

Wang, also a Shanghai native, gained his bachelor's degree in international relations at Fudan University in 2015.

Later, as an exchange student, he spent about eight months at the University of Helsinki, Finland, from 2013 to 2014.

And soon after he returned to Shanghai in June 2017, Wang joined in a nonprofit organization, Serve for China, which recruits Chinese university graduates to work in villages.

The organization, set up by a group of Chinese graduates, helps rural producers sell local agricultural products through e-commerce platforms.

For Wang, rural areas are not a mystery since he grew up in Nanhui, a suburb of Shanghai, with his grandparents.

He moved to Shanghai's downtown with his parents when he was 8 years old, but he still visits his grandparents in Nanhui every week.
