Hi.I found this in the net.
2. A 3rd tone becomes a ‘low tone’ if followed by any other tone
Again, this is confusing at first. It’s probably easier to approach these two rules as “if a third tone isn’t on its own, it changes”. This ‘low tone’ is a low-pitch tone that falls slightly.
<em>As symbols:</em>
[3] [!3] ⇒ [low tone] [!3]
(here the ! represents ‘not’)
<em>Examples:</em>
考试 (exam): kǎoshì ⇒ <em>kao</em> shì
语言 (language): yǔyán ⇒ <em>yu</em> yán
马车 (cart): mǎchē ⇒ <em>ma</em> chē
(In these examples, <em>italics</em> is used to represent ‘low tone’)
Does this means 3rd tone will become nornal tone?
