Why do we need a cover on toilet bowl?

Many of us may not think about it. BUT~~~~~~~~~~
Always close the toilet cover during flushing moment....

Accroding to New York University, Prof.Philip mentioned that, during flushing,the
flusher can actually push the virus and bacteria out from the toilet bowl
to the indoor if the cover it open. According to study, it may be up to
6metre high.

As a result, most of the toiletries will be contaminated if we flush when
the cover is open

So, please close the cover while you flush. For your own health and safety

I always have the toilet bowl covered...it looks better than open too.
