Jay Chou's Qilixiang refers to the chicken butt, which is a very famous snack in Taiwan Province, Jay Chou's hometown. It is called Qilixiang because the chicken butt is used for barbecue or frying, and then sprinkled with pepper noodles and various seasoning powders, even if it is ten miles away, it can smell the aroma of this stall. At that time, when Jay Chou wrote this song, he didn't expect it to be an instant hit. After that, being found out the truth also made many people laugh and cry.

Because Qilixiang is very romantic in this song, when people know that what they are referring to is actually a chicken's ass, many netizens take back what they said. Because the chicken butt is poisonous to mainlanders, when buying food in the vegetable market, the boss will also remind you that you must dig off the chicken butt before you can eat it.

Old people are even more ignorant of chicken's ass. Some people even say that all the toxins on a chicken are collected in the chicken's ass, and their children will not be allowed to eat it. Therefore, even if this kind of food is very popular in Taiwan Province, it has not been circulated in mainland China. Not only that, but no merchant will put chicken butt as a snack.

Jay Chou really likes this kind of food. Not only that, but also it can be seen in many interviews that he is a very grounded person and often goes to the streets of Taiwan Province to eat these childhood memories, so for him, Qilixiang has become an indispensable part of his life.
