What you probably do
You likely use your existing Mandarin u vowel for English words like 'food' and 'blue', rounding your lips tightly and raising the back of your tongue high, which is already a very close match and usually sounds clear and natural.
How natives do it
Americans round their lips tightly and raise the tongue high and back in the same way, though after sounds like t, d, or n, many speakers pull the tongue slightly forward, as in 'tune' or 'dude', giving the vowel a brighter quality in those contexts.
Why it matters
Since this vowel is one of the closest matches between Mandarin and English, it's rarely your top priority; the main thing to watch is not substituting this same tense, rounded vowel for the shorter, looser vowel in words like 'book' or 'full'.
Hear the difference
Words this touches
Mandarin Chinese speakers often substitute /u/.
How the mouth differs
Mandarin u is a high, back, strongly rounded vowel very close to English u in quality; the main difference is that General American often fronts this vowel somewhat, especially after coronal consonants like t, d, and n, while Mandarin u remains consistently fully back regardless of context.
Listen for the pattern
This vowel rarely causes confusion on its own since the match to Mandarin u is close; the more frequent issue is using this same tense vowel for the separate lax English vowel in words like 'book' or 'full'.
