Should the balcony be sealed or not?

If the space is large enough, it can be left unenclosed – such a space is well ventilated.

It is best not to stick tiles, long-term exposure to the sun is not good and easy to spoil. The best way is to make a landscape with rain flower stone and put some plants.

According to tests, when flushing toilets, water mist can fly up to a meter high, which can carry up bacteria. So it's better to close the lid for more hygiene.

It's better not to, or you'll be like me, miserable in the sewer one morning, or be diligent and throw it into the paper!!

Providing toilet paper is a public welfare, of course, it should, but now the individual quality is low (stealing), which affects everyone's enjoyment.
