Guan Changyun was a bit better off; he was doted on by his grandparents and mother, but without a father, his personality was very rebellious, often unable to stand seeing others bully Gouzi and the rest.
Therefore, their relationship was very strong; the saying that the four of them were inseparable wasn't an overstatement.
Even though Guan Changyun was a few years younger than the rest, he had been smarter and more capable in a fight since he was young. They often got ganged up on and chased by other kids in the village due to family reasons, but Changyun was tough enough to protect them and encourage them to fight back. As a result, they won fights, but all four would end up with injuries.
When the beaten kids called their parents over, the parents would come and berate them. The house visited most often was Changyun's, for he was the one who beat those kids most brutally.
