Wang Lang
When Yu Fan became older, he served as an Officer of Merit (功曹) under Wang Lang, the Administrator (太守) of Kuaiji Commandery. In 196, the warlord Sun Ce, who was on a series of military campaigns in the Jiangdong (or Wu) region and had already conquered some territories, prepared to attack Kuaiji. Yu Fan was mourning the death of his father when he received news that Sun Ce was going to attack Kuaiji, so he rushed from his home to the commandery office and asked to meet Wang Lang. He was still dressed in mourning garments then. After entering the office, Yu Fan removed his mourning garments and urged Wang Lang to avoid confrontation with Sun Ce. Wang Lang ignored his advice and was defeated in battle by Sun Ce.
