Meaning:
“原生” means “original,” and “家庭” means “family.” This term, translated from the English term “one’s family of origin,” refers to the family unit in which one was raised. This is not necessarily one’s biological family; your biological family might have little to do with your development if they did not raise you. The term “family of origin” specifically refers to the small unit that cared for you as a child. Your family of origin has a considerable impact on your development. As many studies can attest, your family of origin helps to shape your world view, determines how you relate to and interact with others, and has a big effect on your mental and physical health.
Example:
A: 为什么丽丽和现在的男朋友恋爱十年了还不结婚？
Wèishénme lìlì hé xiànzài de nánpéngyou liàn’ài shínián le hái bù jiéhūn？
Why are Lily and her boyfriend of 10 years not married yet?
B: 可能因为原生家庭不幸福，所以害怕进入婚姻吧。
Kěnéng yīnwèi yuánshēng jiātíng bú xìngfú，suǒyǐ hàipà jìnrù hūnyīn ba。
Perhaps she came from an unhappy family of origin, and is scared of marriage.
