In Chicago, when they some businesses closed "until further notice", does it might mean that former Chicago Mayor Richard M. Daley dies? ?

No, that means there is no fixed date for them to reopen if they ever do.

Ask someone who speaks English to help you compose a question that makes sense. 

No, it means until people stop doing stupid stuff that spreads COVID-19 and start behaving like the responsible citizens of countries that got it under control.

They are probably closed because of state/local rules closing restaurants and bars; or they are losing so much money, they are determining whether they should shut down permanently.

PS: What does this have to do with Richie Daley?  He was a crook like his dad, and we hear nothing about him any longer.

i dont think thats why, it could be cause of covid
