In the nationwide campaign for the production of iron and steel, too many small blast furnaces were built with a waste of material, money, and manpower. This, of course, was a rather big loss. On the other hand, through the campaign we have been able to conduct a preliminary geological survey across the country, train many technicians, temper the vast numbers of cadres and raise their level. Though we paid a steep tuition (we spent over 2,000 million yuan to subsidize the effort), there were gains as well as losses in this endeavor.
