Next month I’m traveling to China on business.
During winter break, I watched the meteor shower in China.
Why did Japanese people stop calling China "Shina" and start calling it "Chuugoku?"
The middle country... who could that be? Let's think about it. Who invented kanji and therefore probably thinks they're the middle of the world? Who also is just a huge country that ruled much of Asia? That would be none other than China.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well. Just make sure you watch out for the rendaku.
