For some reasons, I often thought that he's the weakest among 東邪, 西毒, 南帝, and 北丐, probably because he had not done anything memorable. I guess I could have put him as number 7 or number 8, but since I have already decided that 東邪, 西毒, and 南帝 are all better than 楊過, and 洪 is often said to be their equal, so I thought I should put him ahead of 楊, too.
