When did Deng Shiying become G.E.M.?

Your downstairs is wrong. G.E.M., formerly known as Deng Shiying, was born in Shanghai on August 9, 1989. 1997 went to Hong Kong with his family, and changed its name to G.E.M. (meaning the Hong Kong flag of Bauhinia ~). So from that year on, her name was G.E.M., whether she made her debut or not. Thank you.
