Smoking law - up in smoke?

It was recently announced that from May 1 smoking will be completely banned in medical facilities, nurseries, kindergartens, educational institutions, cinemas, concert venues, museums, libraries, children’s play areas, buses, taxis, trains, train stations, tourist attractions, sports venues and, according to the official press release, all public areas across the city.















So, now there is a big discussion about what is "public areas". The law do not give any definition so it is up to the smokers to decide if it is a "public area" or not?Same thing with smoking in parks and Internet cates that will be "partly banned" - what parts?
Restaurateurs and bar owners, meanwhile, are allowed to implement the ban at their own discretion. However, it's unlikely that many venues will choose to do so.
Originally, the government had wanted Beijing restaurants and bars to dedicate over 70 percent of floor space to non-smokers.This never came to pass due to complaints that the law would lead to a decline in custom. It's well known that many Chinese enjoy a cigarette at mealtimes – little surprise considering China is home to around 25% percent of the world's estimated 1.3 billion smokers - smoking more than 30% of all cigarettes in the world.
