Wuchang rice is a geographical indication brand in China, so it is limited to geographical location, not variety type. So in principle, only Wuchang rice can be called Wuchang rice. However, because Wuchang rice originally belonged to the rice specially supplied by the national government and formed a brand like Wuchang rice, similar rice grown in other nearby areas was acquired and recognized by Wuchang rice brand company, which can also be called Wuchang rice. Just like Harbin beer, Wuhan also produces similar drinks with similar technology and taste.
