The North Korean government is cracking down on corruption, and other "anti-state" behavior. This includes the emergence of some bizarre children's games. In one of them, the kids imitate funerals. It is believed this arose during the 1990s, when so many people were dying of starvation, and there were so many funerals, that kids, as kids are wont to do, adopted the funeral practices of their elders as a form of play. Kids could also be seen playing "firing squad." This apparently developed from kids getting to see frequent public executions of "enemies of the people." The government wants to stamp out these morbid, and unnerving, practices, and has threatened parents with punishment if they do not maintain better control over their kids. More serious sanctions have been administered to those who run trading companies that deal with China. The North Korean trading officials had been keeping two sets of books, the one the government was shown listed much lower prices for North Korean goods sold to China. The bureaucrats running the government approved trading companies kept the difference between the low price and the real price. But many of these guys could nor resist spending their profits, building mansions and buying foreign cars. This attracted the attention of the police. At first, the cops were put off with bribes. But this year, a new bunch of anti-corruption police arrived in the towns along the Chinese border. Investigations and executions (of police and trading officials) followed.
