my teacher say pk and other 粗口 ?

其實你老師係用英文粗口黎串d學生/用黎鬧學生
其實有3個方法既:
1. 可以向其他老師投訴, 可能一個講, 其他老師/校長會唔信
但係如果好多學生都咁講, 學校就可能會施加壓力係個位老師身上
2. 直接同家長講, 等家長向學校投訴
3. 向教統局投訴, 尤其係個位老師用粗口鬧學生, 令學生感到不安/受辱
好大可能會受到處分

(不過小心個位老師會向學生報復)

complaint
or if u r fd with ur teacher,tell he/she not to say that again as it really makes u feeling uncomfortable.

不要理會他/她,並告知父母,讓他們幫你吧!他們會很樂意幫你的,十萬個放心吧,我絕對支持你!!!加油!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

向校長和教署投訴，也可以向傳媒投訴，讓事件向公眾曝光，更多人會關注。
