The first Tropical Fruit Industry Expo was held in Sanya, Hainan Province, on Thursday.
The expo attracted more than 150 purchasing agents at home and abroad.
A kind of "fruit corn" has become the new favorite.
"Fruit corn" is still a grain, but it is juicy, crisp and sweet, and can be eaten raw.
The planting and transportation process of "fruit corn" requires a lot from the external environment and temperature.
It has been sold across the country via cold chain transportation.
