compared to modern chinese, old chinese likely had inflectional morphology, with a case system shown in personal pronoun at least, like its cousins in the sino-tibetan branch. It also had a complex consonant cluster, the consonants likely played a role in inflection, if its anything similar to classical Tibetan. Modern lhasa tibetan also lost its consonant clusters and developed a simple tone system to compensate, while amdo tibetan remained similar to classical tibetan phonology and never developed tone system. The development of tones in chinese is likely an influence from other mainland SEA languages, along with grammatical similarities.
