BUTTERWORTH: Roads outside schools were abuzz as Year Three to Six pupils returned to classrooms, with many parents choosing to personally drop off their children. At SJK(C) Li Hwa here, a stream of vehicles was seen queuing up outside during the morning session. The queue eventually stretched for about a kilometre as pupils bid goodbye to their parents and lugged their bags into classrooms after they were dropped off within the school compound. Teachers and security guards took on additional roles to make sure traffic was in order, while a few other teachers were armed with hand sanitisers and temperature scanners to ensure pupils had their temperature checked and hands sanitised.
