如果你覺得那些問題該問,那你可以回:
Sorry I have to bother you again, I am a little confused by your answer above. Are you the right person for my questions?If not, could you let me know who is the right POC? Or do you have a mailing list for this kind of questions?
你的問題如果問的太細小,也許他說的是還有其他人可以問,不必問他,他已經有很多人問他關於更大的項目的問題。
