The elder brother protects the side, the younger brother protects the interior, the elder sister protects the wisdom, and the younger brother protects the heart.
Four people are on different battlefields, fighting for the same belief.
Seizing the direct descendant is not the goal, protection is.
Giving in is not giving in, but taking on greater responsibility.
The wind blows at night, and the road to rivers and lakes is far away.
Above the court, there is my brother's sword; beyond the border, there is my brother's city; in the rivers and lakes, there is my own wine.
This life is enough.
