In a past life, Tao Yinyin's aunt worked as a maid in a wealthy household. The lady of the house, Liu Mingzhu, was pregnant, and the maid's sister-in-law was also expecting.
As a result, the maid's family harbored sinister thoughts.
On the day that Liu Mingzhu gave birth, the maid did not call Tao Tiancheng. Instead, amid the chaos, after Liu Mingzhu had given birth, the maid swapped her own niece with the newborn.
Only after the swap was completed did she call Tao Tiancheng and Liu Mingzhu's parents.
When everyone arrived at the hospital, they saw Tao Yinyin, who had already been swapped, and when Liu Mingzhu woke up, she too saw Tao Yinyin. Only Tao Bin, returning from Shaolin Temple, felt something was amiss, saying his little sister did not resemble them when they were two hours old.
At that time, Liu Mingzhu laughed and said that they were boys and Tao Yinyin was a girl; they were different.
Being young at the time, Tao Bin did not dwell on it any further.
