Koreans have a bad temper. There are good people and bad people everywhere. We can't generalize. Korean students in our school are really polite to people, but I think they have to be polite because they are in a foreign land. I heard that many Koreans look down on China people. Far away, Sun didn't kneel down to Boss Han (that smelly woman asked all China employees in the factory to kneel down to him). Recently, a Korean couple forced a kindergarten teacher in China to kneel to them (the Korean kid bullied them). Koreans seem to like to be knelt down by others and also like to kneel down. One day, Korean students in my city collectively knelt down in the downtown square and hugged each other and cried (it is said that this can exercise their will), which always felt a little abnormal. I only know these things around me. I know a Korean who likes to brag very much. He said he was Won Bin's partner in his hometown, but I didn't believe him.
