And they're well matched. 势均力敌

238. In the outskirts of Hara in Ethiopia,
     在埃塞俄比亚哈拉市郊外
239. two clans are coming face to face to battle over a prized resource.
     两群鬣狗针锋相对 准备争夺宝贵资源
240. There are about 60 hyenas in each clan.
     两边队伍各有六十只左右
241. And they're well matched.
     势均力敌
242. After three hours of posturing back and forth,
     经过三小时的来回周旋
243. the losers retreat
     一支队伍败退
244. and the victors head to claim their prize.
     赢家则出发去享受战果
