It is unlikely that it will snow in Shanghai. Shanghai is located in the low latitude area, far away from the cold air mass source area in the high latitude area. In addition, many east-west mountains in China can effectively block the cold air from the source area of cold air mass in high latitudes, so the probability of snowfall in Shanghai is low. Shanghai is the financial center of China. There are Shanghai Stock Exchange, Futures Exchange, China Financial Exchange, Shanghai Diamond Exchange, Gold Exchange, Financial Derivatives Exchange, Inter-bank Bond Market, China Foreign Exchange Trading Center, China Capital Lending Market, National Gold Reserve Operation Center, National Foreign Exchange Reserve Operation Center, Shanghai Clearing House (China People's Bank Clearing Center), China People's Bank Shanghai Headquarters (central bank credit information system center, throttle data processing center), Shanghai headquarters of China's four major banks (Agricultural Bank of China, Bank of China, Industrial and Commercial Bank of China and China Construction Bank), Greater China headquarters of major foreign banks, China Anti-Money Laundering Fund Monitoring Center, Shanghai Interbank Offered Rate, China Insurance Exchange and other different financial institutions.
