Opening a Mahjong business. Does 熬云 sound like a business name? Have no idea what a normal Chinese business name sounds like I believe this violates rules (at least it does in StackOverflow), because it's a subjective question.  But this is a really big decision so I just wanted to tap any resources I could before moving forward

I'm going to open a business that has private Mahjong rooms, open late (till 4AM), at the top floor of a building

For a business name I am thinking

熬云

Because 熬夜 is staying up late
运气 is luck
and 云 is clouds (top floor)

But my main problem is that I have no idea how it sounds.  I do not know any Chinese business names, what is normal, what sounds normal, what sounds ridiculous

So my question is:
Does 熬云 sound like a business name?  Especially one that has private rooms for mahjong
To me as a native speaker, there is a negative feeling about 熬. It means getting through(or endure) bad things(etc. pain, poor, sickness).
see 熬's meaning here

So maybe 熬 is just not the best choice. But considering your ID as "A O", you may like this "ao" sound very much. So my recommendation is to use 鏖 instead.(see 鏖's meaning here). It basically meaning a really long battle. As Mahjong is a really long battle on the table. Hope this helps.
