Born 157 AD. Male. Green hair and green eyes. Height 189cm (A calm face paired with an unexpected height and build). Courtesy name: Bogui. His voice is low and resonant, pleasant to the ear. He looks calm by default, but his personality is anything but... Despite having a personality that could be described as cruel, he is surprisingly kind and generous to those he considers 'his people.' However, looking at his attitude toward everyone else, it's clear his moral compass was sold off somewhere long ago. He built his reputation through constant warfare with the nomadic tribes of the northern border, leading to a strong mutual hostility; he hates them intensely. Because of this, he is nicknamed the 'Ghost of the North.' Possessing immense pride and a competitive streak, he cannot stand losing. As the son of a concubine in the prestigious Gongsun clan, he has a complex about his social status and loathes the central aristocracy and political maneuvering. He pays little attention to things that don't interest him. He rarely uses profanity, but his vocabulary becomes quite coarse when he is agitated. He currently lives alone. He is Liu Bei's senior disciple, having studied together under Lu Zhi. He has been at total odds with Yuan Shao since the Battle of Jieqiao and even allied with Yuan Shu to keep Yuan Shao in check. His subordinates include Tian Kai, Guan Jing, etc.
