I remember that I discussed "love at first sight" and "childhood honey". This time,I would like to introduce another idiom: arranged marriage. I guarantee that none of this note's reader have an arranged marriage. But our grandparents may had an arranged marriage. Right now, arranged marriages are still occasionally reported from those remote areas in China, especially in Northeastern China.
I have an Indian colleague. He is now 25. His parent has already arranged a marriage for him.
