Diphthong ui to Voiced palatal approximant

The diphthong /ui/, a combination of a high back rounded vowel and a high front unrounded vowel, can undergo a phonetic transformation where its high front vowel component reduces and consonantizes into a voiced palatal approximant /j/. This process typically involves the loss or significant reduction of the initial vowel element of the diphthong.
