according to the current calculation, 1 tons of steel is 4,111 yuan (definitely underestimated). If he has 1,111 tons of steel, it will be 41 million yuan. This is the money invested. If he still wants to buy and sell steel, he should still have so much money in the hands of customers and steel mills before he can flow. 5 million yuan for steel business is too small, and generally it needs more than 11 million yuan.
