Legal analysis: low-income households can open securities accounts, and the relevant national laws and regulations do not clearly stipulate that low-income residents are not allowed to participate in securities investment funds. However, the investment and income of securities investment should be included in the family property income. Once the income and investment do not meet the minimum living conditions, they cannot enjoy the minimum living standard.
