在上海做钢材行业外贸，是机遇还是挑战？
Hello! I am in the steel business. I have been doing this for many years, and I have lived in Shanghai for many years as well. I personally feel that the steel business is not that easy, especially in terms of foreign trade. Please be very cautious, because the price of steel is unstable, changing by the day, and the freight in steel trading is a very serious issue that one cannot avoid. Therefore, investors should be cautious!
