You have enough questions. Let me answer you first: at present, there are only three legal channels for buying and selling gold in China: 1, spot jewelry and gold jewelry store; 2. Bank paper gold or gold bar transactions; 3. China Shanghai Futures Exchange gold futures. The first two items are suitable for you to collect spot gold, and the third item belongs to futures varieties. You must buy and sell through the trading platform of the futures company, which means that you must open an account in the futures company before you can buy and sell. However, individual speculators cannot make physical delivery, and they must close their positions at maturity. Legal person households can only make physical delivery if they obtain relevant qualifications. It seems that you have Zheng Lu futures in Shandong, which is bigger than Luneng Jinsui futures. I haven't heard of anyone else. Except for these three legal channels, the rest are underground gold speculation companies, which are not protected by law. Many of them have been bypassed by overseas institutions. Once the banker has an accident, all the customers will be lost. I guess you heard about the century gold case in Hangzhou in the past year? !
