Yang Zongwei's nickname is Onion. A Xin specially wrote a song called Onion. It expresses that the girl doesn't understand the love that the boy silently pays. She can't see the boy's heart, so the boy is very sad. If she sees the boy's heart layer by layer like an onion, the girl will be moved.

Although A Xin, the creator of Onion, never peeled off Aska Yang's heart layer by layer, he stacked a affectionate Aska Yang layer by layer with melody and words. The lyrics are in line with Aska Yang's feeling. Onion is a kind of food in our life now, and its smell is disliked by many people. However, some people like her, and the composer of this song thinks that Aska Yang's personality is just right for onion, and Aska Yang's characteristics match onion very well, because Yang Zongwei is the kind of person who doesn't like talking very much and is not good at words.

The lyricist wants to tell everyone through this song that you should never miss an opportunity to feel people's true heart. Some people are not what you look like. This onion is like singing Aska Yang himself, and the content of the lyrics in it is also very consistent with the feeling that Aska Yang usually brings to everyone. After peeling the onion, it will make us burst into tears, just as we will also burst into tears after hearing Aska Yang's song with his own heart.

Onions don't look so good on the outside, but after peeling off layers, they will be burst into tears by the smell. Aska Yang's interpretation of Kuqiang is just like the smell of onions, and people can't help but be moved.
