Okay, the user wants me to translate "ex-professionals" into Traditional Chinese. Let me think about the correct term here. "Ex-professionals" refers to former professionals, right? So in Chinese, "former" is usually translated as "前" (qián), and "professionals" would be "專業人士" (zhuānyè rénshì). Putting them together, it should be "前專業人士".
Wait, let me check if there's a more common term. Sometimes "ex-" can also be translated as "前" in this context, like "前員工" for former employees. So "前專業人士" seems accurate. I don't think there's a different translation here. The user specified to use Traditional Chinese, so I need to make sure the characters are correct. No need to change anything if it's already in Traditional, but in this case, the original is in English, so translating to Traditional is necessary. Alright, I'll go with "前專業人士".
