His family emigrated from China to (then British) Hong Kong when he was seven years old. He later moved to the USA. He studied
accounting at the University of Hawaii when hearing his first opera, La bohème; he was immediately sold on it, and switched
to studying voice, first in Hawaii, then at the Manhattan School of Music.
He made his debut in 1987 at the Deutsche Oper Berlin. An excellent career followed: he sang at the Paris Opéra, in Nice, Lyon,
Nancy, at the Teatro dell'Opera in Rome, in Bologna, Genova, Florence, Martina Franca, Amsterdam, Copenhagen, Dublin, Bergen, Riga,
Vilnius, at the Moscow Bolshoj, in Warsaw, Leipzig, Wiesbaden, Bilbao, Lisbon, Sydney, Seattle or at the Colón in Buenos Aires;
and he did a lot of concert work, too, for instance at the Royal Albert Hall in London, the Carnegie Hall in New York, the Vienna
Musikverein, the Berlin Philharmonie or the Tokyo Santori Hall.
His operatic repertory encompassed more than 60 roles, the most important of which were Rodolfo, Calaf, Don José, Roméo,
Alfredo, Duca, Riccardo and Radames. In concert, he sang for instance Beethoven's Ninth Symphony, the Requiems by Mozart and Verdi,
Messiah, Jephtha, Die Schöpfung or Das Lied von der Erde.
In 2000, he became artistic director of Macao International Music Festival; in 2003, he founded Opera Hong Kong and became artistic
director there, as well – in both cases, a long-term artistic director: at the time of writing (2025), he still holds both posts.
But he didn't quit the stage; on the contrary, his career was very long, and he at least occasionally performed well into the 2020s.
