Because Fusang Island is now the stronghold of the Eastern Yi people, the officials of the Great Yu Dynasty believed, wishfully, that the pirates coming from Fusang Island were all Eastern Yi people.
In fact, there were not many Eastern Yi people among the pirates; most of them were Fusang pirates driven away by the Eastern Yi people.
But the Eastern Yi people, misunderstood by the Great Yu Dynasty, couldn't be bothered to explain.
They are not yet powerful enough; otherwise, they would retaliate against the Great Yu Dynasty and return to their homeland.
Seeing the defeated Fusang people raid and weaken the forces of the Great Yu Dynasty, they were pleased and even secretly supported them.
These pirates, now cast overseas, are located in the southern part of the East Sea and their influence is continuously extending southward, forming a loose alliance with the coastal aristocrats called the East Sea Gang.
