This drama is about cloning of Human!
Lets look at the Title in Japanese is Bunshin, which if read in Mandarin is Fen Sheng.
BUT! if read in Hokkien or Taiwanese's Min Nan Yu is Boon Sin.
So, Japanese as I have noticed for quite a while, sounds pretty like Hokkien or Min Nan Yu!
Now, why make clones?
Again all the non-virtues or poisons at play!
Resulted in much lost of lives and caused extreme suffering to many.
Buddha Dharma is in everything you can see, feel, hear, touch, sense, and these 5 ying demons can be transform with ease and at will by a True Yogi!
Cheers and Have Fun!
