1. According to the provisions of the Criminal Law and the Opinions of the Supreme Court on Voluntary Surrender and Meritorious Service, under normal circumstances, a person who voluntarily surrenders to the police station after being notified by telephone and truthfully confesses the facts of the crime shall be deemed as voluntary surrender.
2. Not only do you have to eat when you are in hospital, but you also have to eat when you are not in hospital, so this is not due to injury. I believe that the relevant transportation expenses will be supported, because if you are not injured, there will be no such expenses, and whether you are injured or not, food expenses will be incurred. Reasonable nutrition expenses and other expenses should also be supported.
3. If you don't file a case, you can't be wanted online.
