It's Wang Mingyuan in Chinese. The last (rarish) character can be read wan or yuan, but Roy Schmidt met him and reports it was yuan.John Fairbairn : ViciousMan: Although pinyin goes for Wan, yes, Taiwan uses a different dialect, so it likely is "Yuan" in Taiwanese.
O Meien's non-standard opening moves are called "meienisms". -- Vesa Laatikainen
