A story from The Romance of the Three Kingdoms should be written in vernacular, preferably 450 words, and I will be grateful.

Zhuge Liang arrived at Qishan and decided to send a group of troops to occupy Jieting (now southeast of Zhuanglang, Gansu) as a stronghold. Who will lead this team? At that time, he was surrounded by several experienced veterans. But it was of no use to him. He only wanted to join the army.

Ma Di has indeed read a lot of military books and likes to talk about military affairs. Zhuge Liang came to him to discuss war, and he kept talking and came up with some good ideas. Therefore Zhuge Liang trusted him very much. But when Liu Bei was still alive, he saw that Ma Su was not very practical. Before his death, he specifically warned Zhuge Liang, saying: "Ma Di is exaggerating. We cannot send him to do big things. He must be investigated carefully." But Zhuge Liang did not take these words to heart. This time, he sent Ma Su as the vanguard and Wang Ping as his deputy.

Ma Di and Wang Ping led their troops to Xianting. Zhang He's Wei army was also approaching from the east. Ma Su looked at the terrain and said to Wang Ping: "The terrain in this area is dangerous. There is a mountain next to the street pavilion. We just happened to camp on the mountain and set up an ambush." ??

Wang Ping reminded him: "The Prime Minister was leaving before he left. I have been told to hold on to the city and secure the camp. It is too risky to camp on the mountain."

Ma Su had no experience in fighting and thought he was familiar with military literature. He did not listen to Wang Ping's advice and insisted on camping on the mountain. Set up camp. Wang Ping's repeated attempts to persuade Ma Su were of no use, so he had no choice but to beg Ma Su to allocate him a thousand men and horses to station at a nearby place at the foot of the mountain.

Zhang He led the Wei army to the street pavilion. He was secretly happy when he saw that Ma Su had abandoned the ready-made city and stationed his troops on the mountain. The mountain was besieged.

Ma Su ordered the soldiers to rush down the mountain several times, but because Zhang He held on to the camp, the Shu army could not break through. Instead, many people were shot to death by random arrows from the Wei army.

The Wei army cut off the water source on the mountain. The Shu army ran out of water on the mountain and could not even cook food. As time passed, they themselves became chaotic. Zhang He saw the right opportunity and launched a general attack. The soldiers of the Shu army fled one after another, and Ma Su couldn't restrain him even if he wanted to. In the end, he had no choice but to break out of the encirclement and escape to the west.

Wang Ping led a thousand men and horses to secure the camp. When he learned that Ma Su had failed, he asked his soldiers to beat drums as hard as they could and pretend to attack. Zhang He suspected that the Shu army had an ambush and did not dare to approach them. Wang Ping organized his troops and retreated back calmly. Not only did he not lose any of his thousand men and horses, he also took in many of Ma Di's skirmishers.

The street pavilion was lost. The Shu army lost important strongholds and many men. In order to avoid greater losses, Zhuge Liang decided to withdraw all his troops to Hanzhong.
