There are many people in this world who are sick but cannot afford medical expenses. My father was in this predicament two years ago. Fortunately, we got a lot of help from people. Before that, I sometimes donated money when I saw someone asking for help on the Internet. But after that, as long as I see someone asking for help, I will definitely donate no matter how much money I can help. Because I have been helped by others, but also know the despair and helplessness of people who are sick but eager to use money to treat the disease.
