Sorry, at the moment I don't have Chinese software and have to write in English.
Smoking is a matter of both habit and economics only half working.
There are more male smokers in China, but now there are more female smokers in industrialised countries, as a result of their sex revolution or movement in recent decades.
Chins has been opening up and is catching up with those countries, so it is highly likely that more ladies will be smokers in China in the coming decades, although it may be too long for your current concern.
You said high cigarette taxes. It seems that those are not high enough. The government has many smokers, so it cannot impose too high taxes on cigarette. That is political economy of smoking.
Imagine the taxes are sufficiently high, then most smokers will quit from smoking.
In the early 1950s, China was successful in banning opium smoking and many smokers had to quit.
So smoking can be stopped. It is a matter whether most people want to do it or not.
But you need to consider another point too. If one’s smoking does not affect other people’s health, say to limit smoking in certain areas only, or not in most public areas, do you still want to ban smoking? In that case, you may not want to take away other people’s (those smokers) freedom or rights.
But I have sympathy for your concern for passive smoking, caused by others’ smoking in public areas. The government needs to take actions. Some other countries, like Australia, restrict many public areas from smoking. That may be a good public policy.
