In plain words

The disability certificate (残疾人证) itself pays no money; it is a key. Behind it are several separate benefits, each of which you have to apply for yourself, and none of which comes to your door automatically. On the first visit to the Disabled Persons' Federation (残联), ask about the items on its list one by one, which saves you running back and forth several times.
