Tat Ming Pair
In 1999, Wong co-founded the music production company People Mountain People Sea (人山人海). The company has produced and published albums not only for high-profiled pop singers like Leslie Cheung, Faye Wong, Sandy Lam, Eason Chan, Nicholas Tse and Miriam Yeung but has also published works for indie musicians such as Jason Choi (蔡德才), Gaybird Leung (梁基爵), at17 and PixelToy. To celebrate the end of the millennium in 1999, Wong released an expansive compilation album "Let’s Play Again In The Next Century" (下世紀再嬉戲) which contained songs from his solo career and songs from the catalogue of Tat Ming Pair. An alternate version of the album was also released, entitled "Let’s Play Again and Again In The Next Century" (下世紀再再嬉戲).
