Because I applied for social assistance such as medical assistance or subsistence allowance.

When the hospital stamps, if the patient belongs to a low-income family, this certificate is to prove the patient's family economic status so that he or she can enjoy the corresponding assistance provided by the government.

When the hospital stamps the subsistence allowance certificate, the hospital will stamp it to prove that the patient is indeed eligible for subsistence allowance or other social assistance. In this way, patients can receive more medical assistance and preferential treatment, reducing the financial burden on their families.
