With the Zhai family looking out for him, as long as Zhou Zheng did not commit a huge mistake, the Zhai family would simply remind the Zhou family, and Mother Zhou would help clean up after Zhou Zheng's mess before it escalated into an even bigger problem. It was truly a joint effort between his parents and the Zhai family that Zhou Zheng was able to hold on to his position for so many years.
On the contrary, the Zhai family would no longer try to help Zhou Zheng because of Qiao Zijin. Mother and Father Zhou had initially taken Zhou Ying with them and started to live separately from Zhou Zheng. Without help from the Zhai family, even if Mother Zhou was willing to acknowledge Zhou Zheng as her son and help him, there was no way for her to clean up the mess before the problem had happened anymore.
And because of this, Zhou Zheng was dragged down from his position.
