I once heard from Dr. Tong of an opium addict who's very good at literature: Won all three top prizes with the essay titled "The bad influence of opium" while Xi Sheng Mo (席勝魔) himself was still an addict.
I could not find any other information about him until I heard his name mentioned again when Mefferd interviewed Bob Fu on his book "God's Double Agent".
The name's the same, but I do not find Dr. Tong's account of Xi's story. I did not know that Xi Shengmo had become a pastor. Perhaps there is a biography.
