If you haven't completed the Thaneship questline for your selected Hold, you aren't the Thane and this method won't work. People in the Hold in question will casually refer to you as "Thane" if you are the Thane. You get one free pass for being the Thane if you meet the following conditions:  Your bounty's value must be under 3,000 gold. You must not have used the Thane excuse before. Go to the main city in the Hold in which your bounty is active. This should happen almost immediately, but you can expedite the process by approaching one of the patrolling guards. When the guard accuses you of having a bounty, select I’m the Jarl’s Thane. I demand you let me go at once. in the dialogue box. If you're ever caught with a bounty in this same Hold in the future, the Thane excuse won't be an available option when confronted by a guard.

How would you rephrase that briefly using Chinese?
确保你是发出悬赏的城堡的“领主”。 确保你可以将“领主”当作借口。 进入城堡。 等守卫来找你。 选择“领主”回复。 记住这招只能用一次。
