Treatment of ü
When -ü stays as -ü
There are only four syllables that actually are written with the {ü}. They are {nü, nüe, lü, and lüe}.
When ü- becomes yu-
Syllables beginning with sound /ü/ are written with a {yu} replacing the /ü/.

When -ü becomes -u
Syllables containing the sound /ü/ following the palatals /q, j, and x/ are written with a {u} replacing the /ü/. There is no ambiguity here, because the palatals require the rounded /ü/ sound.
