(牛 栄子, b. 1995-05-12) Japanese female three dan professional.
Qualified in 2015, 2p (30 wins) on 2017-12-22, 3p in 2020.
Runner up in the 2017 Female Kisei, losing to Xie Yimin.
Description by Fairbairn, 9 May 2021:
"She is Michael Redmond's niece, incidentally, and despite her Chinese heritage she was born in Japan. She's 22 ... on 12 May ... She's been a pro since 2015. Despite not quite hitting the headlines she has had a couple of runner-up places in major women's events."
(Presumably) the daughter of professional Niu Lili (former amanuensis to Go Seigen) and her husband, four-time Chinese Xiangqi National Champion Zhao Guorong. Lili is the sister of Niu Xianxian (also professional), who is Redmond's wife.
A note on her name: the Perfect Weiqi Database gives her second kanji as the simplified hanzi and unofficial shinjitai 荣, but the Nihon Ki-in (according to the list of Japanese professionals) supplies it as the official variant 栄 (unless there was a mistranscription). Both are simplifications of the kyujitai 榮. The form 栄 has been cautiously chosen as the leading name in this article.
