However, the Song Family indeed accumulated some wealth because of Song Xin.
The First Song was in the process of selecting a suitable wife, and then something happened to Song Xin.
As for Song Qing, he was entirely different from the First Song. His age was not too far from Song Xin's; they practically grew up together.
Their relationship was quite good, and they disagreed with their parents' plan to marry Song Xin off to a wealthy person.
The Song parents were very displeased with this son for constantly opposing them for Song Xin's sake. They believed Song Xin was inciting him, and every time Song Qing brought up the matter, Song Xin would get punished, which infuriated Song Qing to the point of almost running away from home.
Later, he dared not mention it much, and since their parents forbade them from being too close and as they grew older, their sibling relationship was no longer as close as in childhood.
