That is the story behind the hundreds of years of existence of Hội quán Quảng Đông, one of two remaining Hoa Vietnamese guild halls of Hanoi. According to historical texts, since the end of the first millennium, there has been a steady flow of ancient Chinese migrants moving southwards to settle down in the Red River Delta. They came from all walks of life, from merchants, craftsmen to refugees relocating away from political turbulence, heading to Vietnam to seek new opportunities.
