My sister is stupid and I want to send her to a retard school so she does not embarrass the family anymore. Can you suggest some schools to send her to or how I can convince my parents to send her to one of these schools?

Unfortunately, there is no simple way to convince your parents to send your sister to a special education school, nor is there an easy solution. However, there are certain approaches that you could take which could help make your case stronger. 

1. Research special education schools in your area which specialize in teaching children with developmental or intellectual disabilities, then compile information and provide it to your parents so that they can better understand the options that are available to them.

2. Reach out to professionals in the field and get their advice as to which special education school would be best suppoorted for your sister and your family. 
3. Provide evidence which shows how your sisters behavior affects her as well as the family, such as examples of embarrassing incidents which have happened.

Although it may be daunting, your best bet would be to create an argument which addresses both your parents' concerns as well as the needs of your sister, and to try your best to come up with a solution together with them.
