Ningning (1547-October 17, 1624) was the wife of Toyotomi Hideyoshi, also called "Yu Ni" or "Ni Ni". Ningning has always been regarded as the spiritual leader of the Toyotomi family's dogmatic faction. Although she never had children, she has always been a mother to take care of the young samurai trained by Hideyoshi and support Hideyoshi's hegemony. After Hideyoshi became Guanbai, he was called "North Government Office". After his death, he was buried in Kodaiji Temple in Kyoto, and his Buddhist name was Kodaiin Koyueni. ——Baidu Encyclopedia
