Is it better to be a salesman in a trading company or a manufacturer?

Each has its own advantages. Some customers like to deal with foreign trade companies. They think that foreign trade companies are more professional in English, and they are also very worry-free when placing orders. They don't need to explain to the factory, just tell the foreign trade company what they need. But the price of the factory is more advantageous. Now many factories have their own trade departments, which can export directly and become more and more professional. Moreover, the sales staff of the factory have a better understanding of the products, and the factory can answer the questions or special requirements raised by customers at the first time.
