Why Koreans Don’t Ask “How Are You?” | Cultural Differences Explained

Koreans don't usually ask "How are you?" (e.g. 어떻게 지내요?) Instead, it's more common to ask someone you know if they've eaten. (e.g. 밥 먹었어요?) There are a few reasons for this, but I wanted to ask Koreans what they thought. "Why don't you ask people how they're doing?"

What do you think is the biggest reason?
