China's Miao Minority

If a Chinese Miao minority man is interested in a woman, he would go to the woman's house to ask for her hand in marriage, according to the book 爱心无国界 (Love Has No National Boundaries)

If the woman's family is satisfied with the man, he will be served with two eggs cooked in water. This signifies 好事成双 (or "good things come in pairs").

But if the man is not to the satisfaction of the woman's family, he will only be served with one egg. This meant 一厢情愿 (or "one-sided liking").
