As we go to the restaurant, we need order some dishes. Of course, it is not an easy job to order dishes, even we are in a Chinese restaurant.
Some people are music lovers. They like to call some music radio station to request their favorite songs. Just say we cannot "order a song". No! We can request some songs only. If you request a song to make somebody else happy, it's called "to make a dedication". Usually, people call music radio stations to make a love dedication. A wife can make a love dedication for her husband. A daugther can make a love dedication for her parents. A lover can make a love decication for his/her sweetie.
We may "order a song" in China, but we can make a dedication in Canada and USA only.
