The name "Eight Thousand Flowing Grass Deer" means to be with Jianba forever. She was originally an orphan, in the name of Jian Ba. At that time, she was still very young, but she was not afraid of Jianba and liked Jianba's knife very much. Then she became the vice captain of 1 1 team, a friend, Maxima, Bole. That's how I understand it.
