1. Body mass index is a body mass index calculated by height and weight, which is used to measure the fat content in human body. However, if the body composition and muscle density are not considered, the body mass index can't really reflect a person's health.

2. Health status should be a more comprehensive and scientific evaluation method. A person's physical condition depends not only on the two indicators of height and weight, but also on blood pressure, blood sugar, cholesterol and other aspects. Therefore, it is unreasonable to judge whether it meets the funding conditions simply by body mass index.

3. According to different groups of people and funded projects, adopt scientific and reasonable evaluation methods, such as comprehensive evaluation according to family economic status, academic performance, family background and other factors, so as to better determine the funded objects.

In addition, in order to ensure that students can get timely and effective financial aid, diversified distribution channels should be established, such as direct distribution of financial aid through schools or relevant authorities, so as to improve the timeliness and accuracy of financial aid.

5. Finally, the subsidy system should be fair, transparent and operable, prevent excessive supervision and abuse, and ensure that subsidies really benefit those in need.
