Fill with helium!

No, no.It's too expensive, a balloon costsThe gas costs 5 to 6 yuan. And it can only last about 6 hours. The room that I worked hard to decorate has such a short lifespan, it's not worth it at all.

No, no, no. Wouldn't that ruin the walls? How could we go to such great lengths to destroy a newly decorated wedding room?
