Olympic star Sui 'so happy' to be back

China's Olympic silver medalist Sui Wenjing is back in the rink following a four-month injury layoff, the 23-year-old confirmed on Saturday.

Sui and partner Han Cong finished second in the figure skating pairs at the Pyeongchang Games in February, but missed the chance to defend their world title in Milan last spring due to a bone fatigue fracture in Sui's right foot.

The problem was diagnosed immediately after the duo's Olympic debut in South Korea.
