从前,在北京市东城区一家粮仓里住着一群老鼠。这家有一个小少爷,经常在花园里练武。花园离粮仓不远,老鼠们也常出来偷学小少爷的武功,日久天长,老鼠们也学会了一些三脚猫功夫。后来,这家的隔壁搬来了一家新邻居,养了几只猫,分别叫大虎、二虎和三虎,大虎经常带着二虎和三虎到处去捉老鼠。这三只猫号称天下无敌捉鼠军团。 Once upon a time, a group of rats were housed in a barn in Dongcheng District, Beijing. This is a young master, often in the garden martial arts. Not far from the granary garden, mice often come out and steal the young master martial arts skills, time-honored mice also learned some three-legged cat kung fu. Later, a new neighbor was brought up next door to the house, raising several cats, big tigers, two tigers and three tigers. Big tigers often took two tigers and three tigers everywhere to catch mice. These three cats claim to be invincible all over the world.
