shuāng bāo tāi

(brothers) twins

In Chinese, the word for twins is '双胞胎' (shuāng bāo tāi), which literally translates to 'double' or 'pair' with '胎' referring to '胎儿' (fetus). This term is used to describe two offspring born from the same pregnancy and is commonly used in both conversational and formal contexts to refer to individuals who are born together and share similar characteristics.
