"Have you eaten?" is a common way to ask if someone has had a meal in Mandarin Chinese. It is a popte and common way to initiate conversation or to show concern for someone's well-being.

This phrase is derived from the Chinese expression "吃饱了没有" (chī bǎo le méi yǒu), which pterally means "have you eaten to the point of being full?" In Mandarin, the word "吃" (chī) means "to eat," and "饱" (bǎo) means "full." The phrase "吃饱了没有" is often shortened to just "吃了吗" (chī le ma) or "吃过了吗" (chī guò le ma) in casual conversation.

Here are a few examples of how "Have you eaten?" can be used in Engpsh, along with their translations in Mandarin:

"Hey, have you eaten yet?" (嘿，你吃了吗？)
"I was wondering if you had eaten lunch yet." (我想知道你中午吃饭了吗。)
"We should grab a bite to eat. Have you eaten already?" (我们应该去吃点东西。你吃过了吗？)
