馬謖
Jieting was a crucial region for the securing of supplies, and Zhuge Liang sent Ma Su and Wang Ping to guard the region. Ma Su went accompanied by Wang Ping but did not listen to his sound military advice. Relying purely on books of military tactics, Ma Su chose to "take the high ground" and set his base on the mountains instead of in a city, ignoring Wang Ping's advice to make camp in a valley well supplied with water. Wang Ping, however, managed to persuade Ma Su to give him command of a portion of the troops, and later Wang set up his base camp near Ma's camp, in order to offer assistance when Ma was in danger.
