Physical sickness is explained as the result of contamination by something "unclean," while all sorts of general problems are ascribed to the rousing of "evil demons." Attaching every phenomenon to ghosts in this way does of course raise doubts.
說到最後，生病是沾了「不乾淨」的東西、做事不順利也是衝到「惡煞」，如此將一切現象都放入靈異的框框內，難免招來怪力亂神的質疑聲了。
