注意 （Note）
Even though the pinyin for 你好 is written as “nǐ hǎo”, 你好 is actually pronounced “ní hǎo.” This is due to a tone change that occurs when there are two consecutive third tones. The same is true for “很好“. In the phrase “不太好”, the character “不” also undergoes a tone change to “bú” because of another tone change rule. If these tone change rules seem unfamiliar, see The Tone Change Challenge.
