BEIJING---A bullying（欺凌）incident at a primary school in Beijing should not be bushed off as"a joke that went too far"； rather，faces should be dug out and action should be taken to prevent similar events from happening on campus again，according to experts．
Huang Zifang，a psychologist specializing in children's growth issues，said schools should be careful about taking bullying incidents as mere pranks（恶作剧）．
"Instead，they should work to find out the root cause of the incident in a timely manner，guide the children involved to face and handle the incident in a correct way and teach them to behave properly to avoid-similar situations，"Huang said．
She made the comments after a mother in Beijing posted a description online on Thursday of how her 10-year-old son was bullied at Zhongguancun No 2Primary School，a top school in Haidian district．
The mother wrote that her fourth-grade son was the target of bullies who threw a toilet wastepaper basket at him，striking him in the head．The boy was also mocked by his classmates，she said，bringing on acute stress disorder---a mental illness triggered by severe anxiety．
The mother also wrote that the school described the incident as"a joke that went too far"and that the parents of the boy who threw the basket believed their son was"just being naughty"．
The article went viral，with many internet users recalling being bullied at school．
Shen Xua，a volunteer from Beijing who has traveled the country for several years to work with schools to reduce bullying，said schools should take responsibility for such incidents and try to make the bullies understand that their behavior is"vicious and harmful"and"not allowed"．
"In the long run，a reporting system should be established to root out bullying on campus．Students should be given specific channels to report what they experience to teachers before further mea
