The price of aluminum in Shanghai can guide the price of aluminum in Shanghai. The low price of Lun Aluminum will prompt importers to import a large amount of primary aluminum for profit, which will also become a force to promote the abnormal price difference between Shanghai Aluminum and Lun Aluminum to return to normal. After the change of LUN aluminum futures, Shanghai aluminum will also change.

The price of LUN aluminum has a guiding effect on the price of Shanghai aluminum, while Shanghai aluminum has little influence on Lun aluminum.
