Gold has always been called hard currency, so it is necessary for families with conditions to prepare some gold every day. As for how to invest, the last time I went to Jinyi to buy a gold bracelet, the clerk told me that it is better to invest in gold bars now. After all, as an investment, you don't have to be so fancy, you will save a little craft fee and really worry about your customers. This is so rare and trustworthy.
