Only recently then I know this Taoist sect 'Three King Five Emperor' has a website : http://sanhuangwudi.org/
But there is nothing about opera; it is about its religious activities.
Recently I tried this beer. At first I thought it is a pale black colour but it is like other beers - yellowish gold colour. If you are interested in beer, here is a beer blog: http://beerasia.blogspot.com/
Did you notice people have been using my announcement box at the right column to announce their websites and products. I have not visited any of them.
