In our previous newbie tone change series, we have introduced the tone change rules for 不, 一, two third tones, and three third tones. Just like many other aspects in the Chinese language, tone changes are more nuanced than the rules you see in textbooks.

Practice and familiarize yourselves with the sounds, and you'll be a tone master in no time!
