Influenced by the renewed strength of futures, the quotation of merchants in Shanghai's local management market has shown a large upward trend. As a local market resource mainly operating in Shanghai, Nanjing and Hangzhou, the quotation of local management manufacturers has been adjusted and the price has been raised by 50 yuan/ton. Stimulated by the rise of futures and spot prices, square managers have taken a fresh turn for the better. With the normal arrival of manufacturer's resources, but the resources in the hands of the merchants are not complete, the downstream market has turned better.
