Sure, here's a brief answer in English:
"How are you?" is a common English greeting used to ask about someone's well-being. It can be translated literally as "how are things with you" or more colloquially as "how are ya?" The question is often asked by those who want to know if the person they are speaking with is feeling healthy and happy. In response, people usually say something like "I'm good, thanks for asking" or "I'm doing well, thank you."
