新手請問高人：Voipdiscount 120 天 freedays 意義到底何在？

vd 網站的解釋不甚明了。根據網站的介紹：“Buying credits entitles you to 120 Freedays (unless stated otherwise). This means you can call all countries in the free* destinations list for 120 days at no costs. When the 120 days are over, you will keep your credit, and the normal rate will be charged for these destinations.”可是voipdiscount的free destination list上並沒有中國，打中國是1美分/m。既然如此，對我們來說，Voipdiscount 120 天 freedays 意義到底何在?

小弟實在駑鈍，請前輩賜教！
