In "Bright Sword", after Li Yunlong suffered losses in Zhaojiayu, he quickly organized troops to attack Pingan County. When he assembled his troops, he found that he already had tens of thousands of military forces, so he adopted the method of being besieged on all sides to better speed up the attack. However, when he needed the troops most, he divided the troops and placed them in the direction of the 358 th regiment of Chu Yunfei, and gave the six companies an order to defend for eight hours.

But in fact, after Yamamoto's attack on Zhaojiayu, Chu led the 358th regiment to ambush Yamamoto's secret service team in General Mountain, which shows his heart in World War I, so why invest troops to stop the Japanese army? First of all, this is very important. The direction of brown ditch is only 30 kilometers away from Ping 'an County, and the Japanese cavalry can arrive in less than an hour. There is no room for error, so Li Yunlong must make arrangements in advance.

Second, we should consider the combat capability of Yun Fei's army in Chu. Although Chu occupied the right place and the right time, Li Yunlong still felt that Jin Suijun's fighting capacity in Chu was very weak. As can be seen from the previous battles, although Chu has very strong firepower, it can't be exerted, so he first ordered Liu Lian to help Chu block for a while and let Chu reinforce the position.

Finally, I'm afraid someone is holding me back. Although Li Yunlong thought Chu Yunfei was a man, he was just a colonel. If we don't support him like the battle of Cang Yunling, Li Yunlong will be in big trouble. And determined to fight Pingan county with a regiment, even the neighboring troops did not help, let alone Chu's men. So he sent a strengthening company to the direction of Brown Yanggou, and added the county brigade and the district detachment.

But Chu Yunfei didn't disappoint. After analyzing the situation, he knew that someone was attacking Pingan County. Seeing that the Japanese army was eager to go south, he formulated very strict tactics to stop the Japanese army, and took the initiative to ask the Sixth Company to withdraw from the position and let the 5000 troops of the 358th Regiment stop the Japanese attack, but was rejected by Company Commander Huang. After the efforts of the Sixth Company, Chu led his troops to counterattack the Japanese army many times, causing great casualties to the Japanese army.
