Mainlander's good news is icing on cake after Wang and giant-killer Yip ensure two more medals The Hong Kong badminton camp was in a state of high excitement yesterday as they celebrated another two guaranteed medals - and the conversion of China's Athens Olympics bronze medallist Zhou Mi into an SAR citizen. Zhou's application to join the Hong Kong fold under the government's Quality Migrant Admission Scheme had been successful, the badminton association confirmed. Zhou was dropped from the China national team in March. She is still in Guangxi, but is expected to arrive in Hong Kong after these games to finalise bureaucratic proceedings that would allow her to represent the SAR. Just before the announcement, Hong Kong teenager Yip Pui-yin pulled off one of the biggest surprises on the court. Yip, 19 and ranked 18 in the world, stormed into the singles semis with a stunning 2-0 victory (21-19, 21-19) over world number one Zhang Ning of China, her first win over the Olympic and world champion in four encounters. In another quarter-final, Wang Chen, Hong Kong's top singles player, secured a semi-finals berth with a 23-21, 21-8 win over Lee Yun-hwa of South Korea. The results guarantee two medals for Hong Kong as two bronzes are awarded for the losing semi-finalists. 'I never thought I could beat her [Zhang] in a major games like this,' said Yip, who only turned to full-time training last year after completing secondary school. 'She is my idol in badminton and I almost broke into tears after the victory because I just felt so happy.' Following her first win against Zhang, Yip admitted she was a bit fortunate to succeed, especially in the first set when she fought her way back from 19-15 down to score six points and win. 'It seems that she is not in top form and she made many mistakes,' said Yip. Hong Kong coach Chan Chi-choi heralded the victory as a major breakthrough for Yip after her self belief held firm against the world number one. 'It will certainly be a morale booster for her,' said Chan. 'In the past, she has suffered pangs of doubt about her own ability, but against Zhang, she played the best game I have ever seen from her.' Yip, seeded seven in the tournament, was to take on eighth seed Hwang Hye-yeon of South Korea early today (HK time) for a place in the final while Wang, the third seed, faced a tough task against world number two Xie Xingfang from China. The coach said the Hong Kong team would be further strengthened should Zhou, who is only 27, decide to continue her playing career in Hong Kong, as is expected. 'I am happy to learn that Zhou has chosen to come to Hong Kong through the scheme. If she wants to play badminton in Hong Kong, there should be no problem as she is a top quality player,' said Chan. Zhou, from Guangxi province, started playing badminton at the age of nine. She won her first singles open title at the Dutch Open in 1998. She also won a gold medal at the Asiad four years ago and a bronze medal in the Athens Olympics. However, she was dropped from the mainland's national squad early this year as she did not feature in their plans for the 2008 Games.
