Dong Yun
During the early years of his reign, Liu Shan was not an unwise ruler. While Zhuge Liang was alive, Liu Shan treated him as a father figure, allowing Zhuge to handle all state affairs. Zhuge Liang recommended many trusted officials, including Fei Yi, Dong Yun, Guo Youzhi and Xiang Chong into key positions. Under Zhuge Liang's advice, Liu Shan entered into an alliance with the state of Eastern Wu, helping both states to survive against the much larger state of Cao Wei. During Zhuge Liang's regency, the government was largely efficient and not corrupt, allowing the relatively small state of Shu to prepare itself for military campaigns.
