Doctor or Quack?

Sometimes when the doctors from the hospital can't help you or be it too expensive to go for. People will go for an alternative way to be treated. There is one which I have seen which a lot of people will agree with me that he is a quack. There is once which my parents have heard that there is a "expert" some kind of chinese doctor which is good at healing with just using his hands and some sort of acupressure. I have heard that he is a very bad person as in someone kneel down to beg him to heal and yet he is unmoved. So I went to see him. He is healing people at the HDB block. After that, i think that he seems to have real skills. Maybe not a real quack. But when i see how he so called treat his patients... Well... A most women were treated by him. He always touches the woman's private parts... Well... I don't think that any other doctor will put their hand into the cloths and touch on the private parts, especially chinese doctors. If necessary, they will surely asked before. Luckily, he didn't touch mine!! Well.. whether he is that skilled or not, that is up to you to believe.
There is another case which I heard, a massage guy who do his business at home. There is one woman, which went there for massage, there is only him and that woman at home. And he ask her only to wear something to cover her private parts. And that woman is frightened so she take his pills and strange things happened... She had headache at a certain time at night almost everyday... Lucky she had prayers of 观音 at home. So she stop going there and stop taking his medicine. Now she recovered. Hmm... Is it a case of a black magic?
