Party membership is likewise a function of your songbun, and so in another irony, there aren't any members of the working class in the Korean Workers' Party.

党员身份同样是你们出身党的一项职能， 因此具有讽刺意味的是，朝鲜劳动党中没有任何工人阶级成员。

Because, although you can't get yourself into a higher songbun, if the government finds out you're doing something questionable, you can get knocked into a lower level.

因为， 虽然你不能让自己进入更高的出身， 但如果政府发现你做的事情有问题，你就会被打到较低的等级。
