After watching John Chang on YouTube recently and then reading the Magus Of Java I decided to do some research about him and send sms to my Chinese Indonesian wife's family in Indo to see if they had heard of him. I received 2 replys that said they have never heard of him But I did not give up, I sent the YouTube video to one of my wife's uncle's who watched da video and sent me an sms back saying he knows John Chang but he is known by another name. Chinese Indonesians have their Indo names but also go by their Chinese names when with other Chinese. The uncle advised me that John Chang had been to his place on a number of occasions to work on my wife's Grandfather, (Kungkung) and da uncle I was in touch with. It turns out that my wife is related to John Chang by marriage and John Chang's niece staying with me in Melbourne last year and will be coming again to visit at the end of this year. I was married in Indo, lived and worked their for more than a year and I can speak Indo. As I visit Indonesia once a year and have stayed in John Chang's city on numerous occasions staying with the uncle, my next visit I will set up a consultation with the man known to the west as The Magus Of Java ; Dynamo Jack ; John Chang... BTW my mother is a Traditional Chinese Medicine doctor and I have been studying Philosophy for the last 13 years. My favourite though is Taoism.
