Cui Shaoyuan was the kind of person who could navigate his way through any situation. Although he wasn't the leader during a particular period, he still held considerable power, and his spoken words and actions carried weight. After accomplishing his tasks, he would gracefully step aside to enjoy his twilight years; perhaps that was because he only followed the old leader and never persecuted the loyal and good.
However, it was beneficial and harmless for one's family to befriend such a person during that special period.
Saving his father, indeed put the Cui Family in significant debt of gratitude.
