Hi Cecil, I am very grateful for your reply. It is difficult to find such great person to offer thisto stranger these days. I have checked and indeed I belong to weak yang wood. Is "metal" industry suitable for me? The reason for asking is though the offered company is in plastic injection business, they are also involved in tool making. At the same time, they are also looking into doing metal stamping business. If an offer is very attractive but belonging to the "unfavorable" career, what should one do to avoid the "clash"? Thank you sincerely.
