Da Ling's younger brother was not his blood brother and was only two days younger than Da Ling. Initially, Da Ling's parents took the orphaned younger brother under their care after his parents died of illness, leaving him without any support. Because their ages were close, the younger brother always compared himself to Da Ling but never managed to surpass him. His envy was strong, and he always had a bad relationship with Da Ling, who also had no interest in getting along with him.
Since Da Ling's parents had passed away, they knew about the poor relationship between Da Ling and his brother and left no obligations for Da Ling to take care of his brother. While their parents were alive, the family would occasionally gather for a meal, but after their passing, Da Ling and his younger brother had barely seen each other.
