Tone change you need to know

Two third tones in a row

When a third tone is followed by another third tone, the first one is pronounced as a second tone. 你好 is written nǐ hǎo but said “ní hǎo”. The writing never changes — only the mouth does.

Third tone before any other tone. Before a first, second or fourth tone, the third tone loses its rise entirely and stays low. This “half third” is what you hear in almost all real sentences.
