My friend has asked me how to translate a sign asking people using a bathroom (toilet) at the tourist attraction where she works. She wants to ask that they do not to throw toilet paper in the wastebin/basket but instead to put it in the toilet bowl (and flush).
I'm not good at formal Chinese, but I've done a little research and have come up with this as a suggestion. Could you let me know if it's OK?
请勿将卫生纸入篓
卫生纸应扔进马桶
Thanks!
