二级官模中第5题关于用名片的。

“Jun also receives new business cards which read “Sang-Gyung Jun, CFA, Investment Consultant.” Jun mails letters of introduction with the business cards to contacts and potential clients.”

请教：这个名片为什么用错了？

官书中说“CFA marks must always be used 1) either after a charterholder's name or 2) as adjectives in written documents or oral conversations.”

我觉得没用错啊。请指教！谢谢。
