Advani notched up a 10-9 triumph to set up a clash against England's Robbie Williams in the penultimate qualifying round tomorrow. The main event is scheduled from April 19 to May 5.
Advani was trailing throughout the match against Hang, who scored heavily in many frames.
However, it was the eight-time world champion from India, who used his experience and showed nerves of steel to get past the finish line first.
With only two frames away from defeat, Advani responded to the pressure and won the next three on the trot.
What has made this trip to the UK for Advani even more challenging was when his regular Dubai-based airline failed to check the baggage which resulted in a co-passenger mistakenly exiting with Advani's suitcase from the Manchester airport.
The Indian was without any of his belongings for three days only to receive it the night before his match.
