太史慈
Sun Ce's aides cautioned him, "(Taishi) Ci will not come back if he leaves." However, Sun Ce said, "If Ziyi abandons me, who else can he turn to?" He personally saw Taishi Ci off, held his hand and asked, "When will you return?" Taishi Ci replied, "Not more than 60 days." He kept his word and returned within 60 days.
