Every tian hou has her moment of glory, so even though she may have been surpassed by other tian hou, they in turn will be surpassed by someone else.... But I'm certain that 20, 30 years from now, my A*Mei cds will still occupy a place in my collection of all-time favourites

Btw, she will be interviewed by Huishi from 93.3fm in the program Tonight in Person on Channel News Asia. The interview was recorded today and should be telecast over CNA pretty soon.
