呼叫小黑呼叫小白
[hū jiào xiăo hēi hū jiào xiăo bái]
The name 'Calling Xiaohei and Calling Xiaobai' could refer to calling two different people, one black ('hei' - dark or bad) and one white ('bai' - light or good), symbolizing contrasts in life or perhaps referring to two individuals with very different personalities or situations in life.
