It is unfair to change the Su stick into Su stick, because it is called Su stick. Su Zhu is the cp of Su Xinhaohe, named Su Stick. Because Zhu Zhixin once performed nunchakus by his predecessor Jay Chou, people nicknamed him "Stick". Among the students of tf family, Zhu Zhixin and Su Xinhao are good friends. Later, because it was called Su Stick, it was unfair, so it was changed to Su Stick.
