英语宅家怎么说

In English, we would say "staying home" or "being a homebody". The word "宅家" (zhái jiā) is often translated as "homebody" in English, which refers to someone who enjoys spending time at home and is content with staying in rather than going out. For example, you could say "I'm a bit of a homebody, so I enjoy staying home on the weekends" to explain that you prefer to relax at home rather than going out.
