Do NOT under any circumstances fly into China or within China with a Zippo lighter which has ever been fueled. Whether it is in carry your on or check in luggage, it will set off their bomb sensors. The airport cops must investigate, send reports to state security in the capital, and wait for instructions. That means everyone goes home late and misses whatever was waiting for them. When they determine that YOU are the culprit, you will get a private session to convince you never to return. Also, their light rail stations and big bus stops have petrol sniffers. So when you finally leave the airport, you have to take a cab.
Did this happen to you?
Are Chinese restaurants ok? Lol
It happened to my stepson and his family in Guangzhou. The lighter was my gift and we didn’t speak again for a year.
