May I ask what a small incense burner is used for a balcony alone?

It should be that the landlord believes in worship, you can ask the landlord to "invite" them away, if you also believe in it, you can also put on incense, and then don't rent it.

If you believe, you will have, and if you don't believe, you will not.

There are two possibilities.

First, the air is not good, so they light cigarettes and burn them.

Second, it is said to be unclean in superstition, because if you are a Buddhist believer, there is only one incense burner in your home dedicated to worshipping Buddha.

I guess it's used to insert sandalwood, hehe.

What else could be?

It was the original god that the owner worshipped, but now that he has been asked to leave, only the incense burner has been left, and this is nothing.

There is also a possibility that it is just to worship heaven and earth, and when the incense is made every day, the gods in the past can be used regardless of their status. I think it's possible that I've been enshrined before, but now I'm invited to leave.

Another solution is to ask the landlord directly. Depressed: Huh.

Anyway, it's superstitious.

If you believe it, you believe it, and if you don't believe it, you pull it down!

You see that right.
