It is just as in Japan, where young people have three "taboos" in looking for work--if the work is dangerous, dirty or demeaning. And in Taiwan, you now need to add a fourth--if the job title sounds bad. These are usually unwelcome to young people.
正像日本青少年對求職有著危險的、髒亂的、工時太長太累的三個「戒條」，而目前在台灣，還要加上職務名稱不好聽的，通通都是青少年的「拒絕往來戶」。
