What do you mean by putting seven needles in your rice bowl?

Putting seven needles in a rice bowl is a folk superstition custom, which is usually regarded as praying for peace, health and wealth. However, this practice has no scientific basis and should not be used as the basis for decision-making.

In fact, this practice is very dangerous, because needles may hurt fingers or oral mucosa, leading to infection or other health problems. In addition, needles may also be contaminated, leading to the spread of diseases.

So I suggest you don't put seven needles in your rice bowl or anything like that. For help or advice, please seek professional advice.
