Ma Su
During the campaign against Meng Huo, Ma Su went several tens of li to see Zhuge Liang off. Zhuge Liang told Ma Su: "It's been years since we strategized together, now I ask for your help with your wise and skilled planning." Ma Su answered to Zhuge Liang as such: Zhuge Liang was greatly impressed and followed Ma Su's advice, many times he forgave Meng Huo in order to gain the trust of the people of the South. And so, until the end of Zhuge Liang’s life, the South did not rebel again.
