Wáng Píng appellation Zǐjūn was a Bāxī Dàngqú man. Originally he was adopted by his maternal relatives the Hé clan, and later returned to his surname Wáng. He followed Dù Huò, Piáo Hú to visit Luòyáng, was brevet Colonel, followed Excellency Cáo on campaign to Hànzhōng, and because he surrendered to Xiān-zhǔ [Liú Bèi] was appointed Ivory Gate General and Supplementary General.
Jiànxīng sixth year  he was part of Army Advisor Mǎ Sù’s vanguard. [Mǎ] Sù left water to go up a mountain, the action was disruptive, Píng repeatedly remonstrated [Mǎ] Sù, but [Mǎ] Sù would not agree, and was greatly defeated at Jiētíng. The army was completely scattered, and only Píng’s command of a thousand men, shouted and drummed to maintain themselves, and Wèi General Zhāng Hé suspected there were hidden troops, and did not pursue. Therefore Píng slowly gathered the scattered camps to escape, leading the officers and soldiers back. Chancellor [Zhūgě] Liàng executed Mǎ Sù and Generals Zhāng Xiū and Lǐ Shèng, took away General Huáng Xí’s and other’s troops, but Píng specially met with honor and praise, was appointed Army Advisor, to manage the five divisions and also camp affairs, and was advanced in rank to Suppressing Bandits General, with fief as a precinct Marquis.
Ninth year , [Zhūgě] Liàng besieged Qíshān, and Píng separately defended Nánwéi. Wèi General-in-Chief Sīmǎ [Yì] Xuān-wáng attacked [Zhūgě] Liàng, Zhāng Hé attacked Píng, Píng firmly defended and did not move, and [Zhāng] Hé could not overcome him.
Twelfth year , [Zhūgě] Liàng died at Wǔgōng, the army retreated back, Wèi Yán rebelled, in one battle was defeated, and this was Píng’s achievement. He was promoted to Rear Manager of the Army, Calming Hàn General, and assistant to Chariots and Cavalry General Wú Yī campaign at Hànzhōng, and also office as Administrator of Hànzhōng.
Fifteenth year , he was advanced in fief to Marquis of Ānhàn, and succeeded [Wú] Yī in commanding Hànzhōng.
Yánxī first year  General-in-Chief Jiǎng Wǎn stationed at Miǎnyáng, Píng was moved to Front Protector of the Army, to manage [Jiǎng] Wǎn’s office affairs.
Sixth year , [Jiǎng] Wǎn returned to station at Fú, and appointed Píng as Front Supervisor of the Army, Northern Defense General-in-Chief, with command of Hànzhōng.
Seventh year  spring, Wèi General-in-Chief Cáo Shuǎng led infantry and cavalry of over a hundred thousand toward the Hàn river, and the vanguard was already at Luò valley. At the time Hànzhōng’s defending troops were not even thirty thousand, and all the officers were greatly alarmed.
Someone said: “Now our strength is not sufficient to resist the enemy, and we should firmly defend the two cities of Hàn and Yuè, when encountering the enemy let them pass, and then when ready, the Fú army can be enough to rescue the pass.”
Píng said: “Not so. Hànzhōng to Fú is a thousand lǐ. If the enemy takes the pass, then it will be a disaster. Now it is proper to first send Army Protector Liú [Mǐn] and Army Advisor Dù to occupy Xīngshì, while I serve as the rear guard. If the enemy sends a division toward Huángjīn, I will lead a thousand men down to face them, and when ready the Fú army will arrive. This is the best plan.”
Only Army Protector Liú Mǐn agreed with Píng’s plan, and immediately put it in place. Fú’s various armies and General-in-Chief Fèi Yī from Chéngdū followed and arrived, the Wèi army retreated, as Píng had originally planned.
At the time, Dèng Zhī was in the east, Mǎ Zhōng in the south, Píng at the northern border, and all had famous legacies.
Píng spent his life on military campaign, could not hand write, and the words he knew were not more than ten, but he orally dictated documents, and all were well reasoned and logical. He had people read the Shǐ[jì] and Hàn[shū]’s various Annals and Biographies, listened to them, and knew their overall meaning, and gradually he could discuss them without making mistakes. He strictly obeyed the law, in his words he did not make jokes, and from morning to night, he sat upright all day, without the appearance of a military General, but by nature he was narrow-minded and suspicious, in conduct he took himself lightly, and because of this decreased his own reputation.
Eleventh year  he died, his son Xùn succeeded.
Previously, Gōu Fú of Hànchāng in the same prefecture as Píng was loyal and brave and magnanimous, repeatedly had battle achievements, and his achievements and fame and rank were second to Píng, his office reached Left General, with fief as Marquis of Dàngqú. (1)
