1. Detailed principle of revenue and expenditure: A good financial habit is to establish a detailed statement of revenue and expenditure to record the monthly expenditure and income, which is helpful to understand your actual financial situation and control your expenditure and planned investment.

2. Diversified investment principle: Diversified investment can minimize risks and maximize investment returns. Investors should not concentrate all their funds on one kind of investment, because this practice may lead to significant financial losses once losses occur.

3. Long-term investment principle: financial management should be a long-term plan, which needs careful consideration, planning and implementation in a long period of time to obtain stable and sustained income. The continuous accumulation of wealth requires patience and perseverance.

4. Private customization principle: the demand for financial management varies from person to person, because people's financial management objectives, risk tolerance, age, asset size, income status and other aspects are very different. Therefore, financial planning should be tailored to the actual situation to determine the investment portfolio and fund allocation.

5. Risk control principle: Any investment is accompanied by risks and benefits. When investing in financial management, we must first make clear the risks and expected returns of investment, and then make appropriate decisions on this basis.

6. Prudent choice principle: It is very important to choose institutions and products with good reputation and stability when making financial investment. Individual investors should carefully choose investment varieties, understand the risk situation and avoid following suit. At the same time, they need to keep a clear head to avoid unnecessary economic losses caused by being cheated.

Extended data:

For every financial principle, we need to deeply understand and implement these principles in practice. For example, when making a detailed statement of income and expenditure, you should record every expenditure as detailed as possible, including specific information such as expenditure items, amount and time, so as to better understand your actual situation and adjust and optimize some key expenditures.

In terms of diversification, investors can consider investing their funds in different industries and product varieties to reduce risks and improve returns. However, this kind of diversified investment does not mean random investment, but needs to balance the benefits and risks reasonably and make adjustments according to its own risk tolerance and actual needs.

When choosing suitable investment varieties and institutions, we should pay attention to the evaluation of product safety, liquidity and yield, and choose according to our actual needs and risk tolerance. It is worth noting that even products that seem to break even and have high returns may have risks, so be cautious and avoid blindly following the trend and taking risks.
