"Pearl Ball" originated from the pearl-picking game of the ancient Manchu people. It is widely circulated among the people and is commonly known as "kicking the core", "picking the core" and "throwing the core". According to the records of "General Examination of Qing Dynasty Literature" and other research, it has a history of three or four hundred years. With the continuous migration of the Manchus to the south, the Manchu folk game of pearl-picking has gradually spread to Beijing, Inner Mongolia and other northern regions. At present, "Pearl Ball" has become an official competition event of the ethnic minority sports meeting. Information source: District Cultural Committee Information source: District Cultural Committee
