Sun Yingsha, Wang Manyu, Kuai Man and Chen Yi reached the women's singles semifinals to secure the title of the event for China in advance at the World Table Tennis (WTT) Hong Kong Finals on Friday.

World No. 1 Sun crushed Japan's Miyu Nagasaki 12-10, 11-6, 11-6, 11-1 to meet Kuai in last four, who just defeated Japan's Satsuki Odo 11-6, 4-11, 9-11, 16-14, 11-4, 12-10.

"I didn't compete with her [Nagasaki] for many times in major events," Sun said. "She has her own style, and I tried to adjust myself to a better form during the match."

After beating Joo Cheon-hui of the Republic of Korea 11-7, 11-8, 9-11, 11-5, 11-4, Wang Manyu will face her compatriot Chen Yi who survived an all-Chinese clash against Chen Xingtong 7-11, 11-8, 11-9, 11-7, 11-2.
