Whether the kids are calling others on the phone to invite them to demo classes, hanging out "helping make the place look busy" or looking after younger students, from their point of view, a "part-time job" at a buxiban is relaxed, there's no time restrictions and you can, as they would put it, "goof off."
對孩子來說，到補習班「工讀」，不管是打電話請人來試聽，或是到補習班幫忙「擺陣勢」，協助照顧學弟妹，套一句他們的話，這樣的工作又輕鬆，又沒有時間限制，又可「打屁」（聊天）。
