Imagine a person standing outside a house with a big '无' (no) sign on the door, looking around and saying '家' (home) and '归' (return). The '无' indicates absence, while '家' and '归' remind you of the longing for a home and the inability to return to one.

Be careful when using this phrase; it is often used in serious contexts discussing social issues. Avoid using it lightly or in a joking manner, as it may offend those who are actually experiencing homelessness. Common collocations include '无家可归者' (the homeless) and '无家可归的生活' (the life of being homeless).

While this idiom is not part of the HSK curriculum, it connects to themes of social issues that are relevant at intermediate levels. Students should focus on the structure of idioms and how they express complex ideas succinctly.

In China, the issue of homelessness can be particularly visible in urban areas, where rapid economic development has led to significant disparities. The term 无家可归 is often used in social discussions about migration and urban poverty.

Learners often confuse this idiom with '没家可归' (méi jiā kě guī), which is incorrect. The correct usage is '无家可归' to convey the idea of being homeless.
