英文摘要：

This paper addresses the shared innovations of Sino-Tibetan languages. It presents as evidence six innovations shared by Sino-Tibetan languages, including those of tones, aspirated voiceless stops, affricates, classifiers, prefixes to kinship terms and reduplication, attempting to prove that the hypothesis is theoretically solid that the Sino-Tibetan family comprises Chinese, Dong-Tai （Kam-Tai）, Miao-Yao （Hmong-Mien） and Tibeto-Burman branches. Further reactions in this regard are appreciated.
