In the early matches, there were wins for two Chinese athletes in Class 3 - Zhao Ping and Feng Panfeng.
Feng was a gold medal winner in Beijing and is Class 3 world number one. He could well set the tone for China at the Games and he comfortably defeated the unseeded Kim Jin Sung of Republic of Korea 3-0.
With eight competition tables running consecutively, the first day's schedule is non-stop with 12 hours of almost continuous action with the initial group matches.
The early session also saw wins for Hungary's Andras Csonka and Slovakia's Richard Csejtey in Class 8, and also Florian Merrien of France in Class 3.
China's Sun Churen beat Aaron McKibbin of Great Britain in Class 8. McKibbin said: 'The last few times I played him he was very basic on his serve, he wasn't mixing it up so much.
'But when I played him this time he changed the spin a lot. I was struggling to receive and I made a lot of mistakes. That's probably what cost me, but I can't complain, I tried my best.'
