是你的大哥吗是我的大哥
[shì nĭ de dà gē ma shì wŏ de dà gē]
This translates loosely to 'Are you my elder brother? Am I your elder brother?'. This name reflects a playful tone mixed with confusion and irony, questioning the nature of hierarchical relationships or possibly implying a friendly, equal relationship while poking fun at the formality.
