In which battle was Liu Shuai's slogan "Meet the brave in the narrow road and win"? Please briefly describe this activity.

I'm glad to answer this question for you. It's time for Liu Deng's army to advance into the Dabie Mountains. The following description: The people in the room are highly focused. Liu Bocheng, who has been silent, raised his head slightly and examined every anxious face with his unusually calm and serene eyes. He said, "Comrades! The situation is really serious. We heard the sound of guns chasing the enemy! If we let the enemy behind us arrive and put us in the middle, it will not only affect the strategic leap forward, but also the danger of the whole army! " At this time, his voice changed. He said firmly and forcefully: "Since ancient times, the brave have won the narrow road!" He hit the table with his fist and repeated more loudly: "Now we should use offensive means to deal with the attacking enemy, and the brave will win in the narrow road!" " Do you understand, comrades? From now on, no matter day or night, regardless of the enemy's aircraft and artillery, we must open a bloody road from the enemy's position and rush over! As long as we are firm, brave and not afraid of sacrifice, we will definitely fight! "I hope to adopt it.
