    Simultaneous membership of Tai-Kadai in Li Fang-kuei's Sino-Tibetan and Benedict's Austro-Tai had posed a problem to Zhengzhang, as he had found both of these mutually exclusive proposals to be well-grounded: Sagart's 1990 suggestion that Chinese and Austronesian are genetically related, soon supported by Xing Gongwan, provided a solution to the conundrum, leading Zhengzhang to the present proposal.
