This is inarguably a devastating new trend in China. For the sake of some superstitious belief in good fortune, fish, turtles, and lizards are captured and sealed within poly bags attached to your keyring. A small translation from a danish article makes everything clear to the level of seriousness of the subject matter: "Reportedly, there should be enough air and nutritious liquid to keep the animal alive for two months - subsequently, you will have to buy a new one." These pictures, taken from the same article, leaves nothing to imagination: http://www.dr.dk/Nyheder/Billedserier/2013/03/07204148.htm
