    Nowadays people are making themselves beautiful in Korean ways.
    "Thank goodness you have double eyelids(双眼皮). Your parents will save a lot of money." said a family friend when I was five years old. Double eyelids, which almost all the white people have, are rare among Northeast Asians. Only 25% of South Koreans are born with double eyelids.
    I never quite understood how having double eyelids saved my parents money until this summer. When I came back to Seoul, everywhere I noticed cosmetic surgery clinics(整形诊所) and advertisements with South Korean women—tall, thin, with milky skin, long legs, nice big eyes and perfect noses. I found that South Korean beauty meant looking as "white" as possible.
    Cosmetic surgery has a kind of magical attraction(吸引) to women — the promise of beauty. Women are often sure that suffering is necessary and worthy in order to be beautiful. This suffering is not for nothing. It is believed that beauty leads to attracting a better-looking partner, which then leads to a better-looking child and a better life.
    Appearance is starting to be more important in work places. People with good appearance can have more chances. For example, my 29-year-old brother, who is slim and very tall, gets more job chances than his best friend, who is short and heavy, though both of them came from the same college, had the same good marks in their studies. In fact, many South Koreans believe that physical beauty equals happiness.
