Crossing the Great Q

Yang Lin picked out ten of the tallest men: "You ten, as shield bearers, hold your large shields in front. Your duty is to protect the spearmen and crossbowmen behind you!","You twenty men, as pikemen, wait until after you charge in. When you hear my order, when I shout 'thrust', then thrust your pikes forward; when I shout 'retreat', then pull back your pikes!","Victory in this battle, each person receives one to two silver coins! In the future, there is a chance to be promoted to squad leader! If anyone unfortunately dies in battle, their family will receive one hundred silver coins as compensation!"。
