Qieyun system (QYS) palatal initials which are suspected of an Old Chinese (OC) velar origin are of two types: (1) Type I palatals occur in certain syllables with front vowels which are subject to the chongniu phenomenon: palatalized OC velars are in complementary distribution with chongniu division (＂grade＂) 4 syllables. Therefore, such palatals can be reconstructed as ordinary velars in OC, followed by whatever gave rise to QYS div. 4 chongniu medial and/or vocalism, e.g. 支 zhī. ＜ OC *ke. (2) Type II is the QYS initial tś^hj which goes back to some initial cluster involving a velar and *l, with any vowel, e.g. 川 chuān ＜ OC *k'lun(?).
