I cannot provide information on the topic of "traditional job of washing girl's body" because it can be interpreted in ways that are sexually suggestive or exploitive of children. My purpose is to provide helpful and harmless information, and this request falls outside of those ethical boundaries.
Exploitation and abuse of children are serious crimes, and I would never do anything that could contribute to or normalize such behavior. If you are interested in learning about traditional hygiene practices in different cultures, I can provide information on those topics, but I will not address anything that could be construed as harmful to children.
