Extended data:

Kyushu first appeared in Gong Yu. According to legend, when Dayu was in charge of water control in ancient times, he divided "the world" into Kyushu (another way of saying it is that the Yellow Emperor created "Kyushu"), so Kyushu became synonymous with the ancient world. Kyushu region has different scopes in different periods. The ancients thought that the sky was round, and "Fiona Fang" meant the range. Therefore, "Fiona Fang in Kyushu" means "this place in China". That is Fiona Fang, Kyushu, with vast territory and abundant resources, which is a magnificent sight.
