Can this situation be judged as excessive defense?

It's just a minor injury. It took 10W. You are obsessed with money. If you want to pay, ask him to bring the hospital invoice.

Get a criminal lawyer. In this case, the defensive measures are only slight and excessive. Sentenced to a maximum of three years in prison. If the lawyer is better, he can be detained and suspended. Don't listen to the police and the other side scare you. Some lawyers will scare you into charging you more. Lawyers in Beijing may be more expensive, but it won't exceed 10 thousand yuan. Medical care and nutrition have been delayed, and these messy things have stopped for ten or twenty thousand.
