Smokes in china are dirt cheap ranging from a pack of 20 (cheapest) for 7 (chi Kauai) RMB. It is quite odd, the more you pay, the less you get, as you get relatively more expensive cigarettes the size is like that of a tooth pick, you are afraid you will swallow it and that much less tabacco. Most expensive packs have maybe 10 or so, some less. All lighters usually one cost 1 Kauai but are known for quickly falling a part or shattering upon a simple drop.
There are some places you "should not" smoke but if you are not seen, who will do anything to you?
Welcome to quitting in china...
