The main investment scope of general bond funds covers various bonds such as credit bonds and interest rate bonds. According to regulations, such funds must invest at least 80% of their assets in these types of securities. Local bonds, government bonds, enterprise loan certificates and various forms of medium and long-term bills issued by financial institutions can also be used as investment targets. Some specific types of funds may focus on a specific type or field, such as corporate loan certificates issued by industrial companies or convertible companies, which are clearly reflected in the name.
