One way to hold this word is to put one person at the front of a crowd with a flag held high. Everyone behind can see where their side is and which way to move, just by looking up. The person is not the one giving orders; the person is the one you can see. Both meanings on this page are that same figure, once with real cloth in his hands and once without.
可以把這個字想成一個畫面：一群人的最前面站著一個人，手上的旗舉得高高的。後面的人只要抬頭，就知道自己這一邊在哪裡、該往哪走。他不見得在下命令，他是「看得見的那一個」。這一頁的兩個意思，都是同一個身影：一個手上真的有旗，一個沒有。
