When Bao entered primary school, Pang intended to find a job in her son's school. However, the only vacancy the school had was for a cleaner. Pang accepted the job without hesitation. "I am happy to do anything to be with my son," said Pang. However, because Bao couldn't understand what was being taught in class, Pang soon requested to sit in with him. She has now been her son's "classmate" for seven years. |
