HONG KONG (AFP) - A Hong Kong fortune teller who once advised Asia's richest woman Nina Wang but was later embroiled in a high-profile legal battle over her fortune has renounced feng shui for Christianity, a report said on Thursday.

Bartender-turned-fortune teller Tony Chan, who is set to face trial next month for forging the will of the late Ms Wang, built a career advising clients on feng shui, an ancient Chinese belief system based on harnessing natural and spiritual energies.

He lost a legal battle in 2010 to claim the estimated US$13 billion (S$16 billion) estate of Ms Wang, who Mr Chan said was his lover. The court drama had gripped the city for years with details of his affair with the tycoon.

Now Mr Chan has described feng shui as the work of the devil after he recently embraced Christianity and changed his name from Tony to Peter, the South China Morning Post reported.

"This is the happiest day in my life. It felt like getting married, and I could tell everyone that I am a Christian," he was quoted as saying by the newspaper, which released a photo of him being baptised this week.

Mr Chan lost his court case after a court ruled that a will in his possession was a fake. It said the rightful heir to the fortune was the billionaire's charity, which is run by her siblings.

But the 53-year-old said he is not afraid of going to jail. "Since I have received the greatest salvation... other things don't matter to me any more," he was quoted as saying.

Ms Wang was known for her thrifty nature and outlandish dress and was nicknamed "Little Sweetie" for her pigtail hairstyle. She died of cancer in 2007 aged 69, triggering a bitter public feud over her fortune.
