During every lesson the classroom is filled with laughter. The old people themselves say over and over again that they are a big kindergarten class. One moment they may be running against the wall, the next they may be crawling on the ground on all fours, doggy fashion.
每次上課時，教室裡總是笑聲連連，這群老人家直說自己是在上幼稚園大班：一會兒去撞牆，一會兒在地上學狗爬。
