The Shihwaitoayuan Company was originally a simple farm that grew persimmons. With the rich natural resources of Dongshih, the farm had expanded into a company which put much effort in improving the quality of sweet persimmons. The company had produced “Chiro” and “Fuyo”, two different types of sweet persimmon but both gained much public praises. The company had totally changed the future aspects of the local persimmon industry.
