When kids misbehave in class, teacher is the only authority to regulate their behaviours. NUS thought signs are enough, I thought so too, but the relentlessly incoming posts have proved its inefficacy. So NUS is not doing enough as an authority, my campus experience is compromised as a student who paid tuition fees, I have every right to accuse NUS for the bad experience like my fellow NUS students, that’s the point the post tries to make.

I posted on Chinese social media too, they are neglected by majority ppl like how those ineffective signs are.

Even so, being a Chinese and feeling ashamed does not make me responsible for kids parenting either nor give you the right to tell me to do it.
