我覺得係因為冇人目擊件事點發生,啲老師嚟到只見有學生訓咗係操場,以為佢暈咗先call st john ... 可能小妹妹跌落嚟嗰一刻根本冇流血,大家都唔係醫生又冇望到點發生,好理所當然地用番佢哋平常嘅程序。。。。 我姑媽跳樓過身時都係係一滴血都冇流㗎。。。anyway , 小妹妹r.i.p. 。。。。。
There're many different versions. Some said students are all back to classroom because of smoke from bus. Some said they see people jumping. Some said they see blood.. anyway, I do not see blood and no newspaper shown blood so that's my guess only. let's wait for investigation.
