Japanese macaques, or 'snow monkeys', are highly social animals, with a complex set of relationships between each other. Entrance to the thermal hot springs, which can reach over 40 degrees centigrade, depends upon the social position of the monkey. Only the highest-ranking females and their infants are allowed in.
日本獼猴，又稱「雪猴」，是高度群居動物，相互之間的關係極為複雜。能否或如何進入這個高達攝氏40度的溫泉池塘完全取決於猴子的社會地位，只有地位最高的母猴以及幼子們可獲准進入溫泉泡湯。
短語 you scratch my back and I'll scratch yours 字面意思是你抓我的背我就抓你的背，用來表示人與人之間的互通有無的互助關係：你幫我一個忙我就幫你一個忙，相互幫助。
