If the tribes still have self-autonomy and their mother tongue has not been lost, even though they've switched to Han surnames, their close interpersonal relationships will still allow everyone to call each other by their traditional names and know whose child everyone is.
如果部落的控制力量還在、母語尚未流失，即使改了漢姓，由於人際關係密切，彼此還可以用傳統命名稱呼，知道對方是哪一家、誰的孩子。
