The persona of a Minister 国士之风 (guó shì zhī fēng)
Who is he:
Historically, Ling Tong was one of the most important generals under Sun Quan 孙权's command. Yet in the semi-fictional ROTK story, Ling Tong was not given much airtime. Ling Tong was put in as high regard as Lu Meng 吕蒙 and Gan Ning 甘宁, and succeeded in numerous battles as well. He is also one of those that is well remembered for having saved Sun Quan's arse from certain defeat. In his latter days, Ling Tong not longer took to the frontlines, but instead became a successful strategist and advisor to Sun Quan.
An interesting side story is his grudge against Gan Ning. When Ling Tong was 15 years old, his father was killed by Gan Ning. At that time, Gan Ning had yet to cross over to Sun Ce's side and in an odd-twist of fate, Gan Ning fired a stray arrow that struck down Ling Tong's father. That grudge nearly boiled over later on as Ling Tong and Gan Ning took to swords to settle the score, but was mediated quickly by onlookers.
