The initial: z
[ts]
- What the mouth does
- Tongue tip at the back of the upper teeth, released as one tight “ts” with no puff.
- Closest English sound
- The ds in “kids”, but at the start of a syllable — a position English never allows.
- Where learners slip
- Reading z as English “zzz”, which is a different sound entirely.
- Drill that fixes it
- Say “kids”, isolate the “ds”, then put it in front of a vowel: ds-a → za.
The final: -ai
[aɪ]
- What the mouth does
- Starts wide open on a, glides up to a short i. The first half carries the weight.
- Closest English sound
- The i in “eye”.
- Where learners slip
- Giving both halves equal length, which makes the syllable drag.
- Drill that fixes it
- Long a, short i: “AAA-i”, not “ah-EE”.

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.
