When facing Wang, the Rocket dominated the table since the beginning of the clash. The 48-year-old veteran only suffered some setback in the third frame, but he adjusted his situation and bagged an easy win without any replies from Wang.

"I've played pretty terrible for two years, so every match is felt rubbish. I've just got to try and look at longer term to try and play my way out of it. But you just have to keep showing up and trying doing your best," he said.

"I'm looking forward to it, the longer I can stand. All the more dinners I can have here in China should be good. I just come for dinner, the people and the culture; snooker is a bonus," O'Sullivan added.
