Asian countries are apparently bracing themselves for next week’s Lunar New Year celebrations and the corresponding uptick in gambling and debauchery.

As tens of millions of Chinese citizens head home for the holidays – believed to be the planet’s largest annual human migration – Chinese airline pilots have been told to quit enjoying themselves and keep their minds on their work.

In an open letter published Wednesday on an aviation website, the China Airline Pilots Association warned their members to cut out the gambling, prostitutes, smuggling and drunk driving. (And, presumably, drunk flying prostitutes to Macau for some gambling).

The Association said “very few” of its members were super depraved but that the aforementioned forbidden fruits were the type of thing that “severely challenges legal and moral bottom lines.” (Although it does potentially offer you a form of immortality via your very own episode of airline disaster recreation show Mayday.)
