The word fence has different meanings. As a noun, it can denote a barrier or divider. Robert Frost has the well known line, "Good fences make good neighbors," in his poem "Mending Wall." In a different realm, the verb "to fence" describes a sport of swordsmanship where opponents use blunted foils, epees or sabers to register hits on each other. But there is third totally different meaning. The noun fence also can describe a person who receives and sells stolen goods or who acts as a conduit for stolen goods; this is the meaning that Taiwanese need to become aware of because it concerns their President.
