The Paris Olympic Games: As the Paris Olympic Games surfing competition is expected to start on Saturday, Chinese coach Luo Yang is cautious despite the excitement of China's debut on the Olympic waves with 15-year-old Yang Siqi.

"Yang has never surfed in Teahupo'o before," said Luo, referring to the Olympic surfing venue in Tahiti famous for its mighty waves, reported by Xinhua.

"We don't have such conditions in China, nor have we encountered such waves during our overseas training. We had two weeks of training ahead of the Games, but compared with some top athletes who have long surfed here, we still have much to learn," Luo told Xinhua.
