Signese

I don't get it.

Also, isn't 洁 simplified, with 潔 as the traditional?

Also, what does 約潔 mean?

Thanks for your interest in this blog.

It is a typo. The message should be 約滿結業.

OK, I get it now.

I read the sign as 滿業約洁 -- "entire store/business something something".

"Reserves cleaning?"

Few people know how to or want to go through the trouble of typing horizontally and vertically on the same page.
