Olympic champion Shaoang Liu returned to competition with a pair of titles as the International Skating Union Short Track World Cup season began in Montreal.

Liu, and his brother Shaolin Sándor, previously competed for Hungary but both opted to switch to China, meaning they had to take a year out of the sport.

Shaoang won the 500 metres title for his former nation at Beijing 2022 and won over the same distance at the circuit's curtain raiser at the Maurice-Richard Arena.

Both brothers were then part of China's victory in the mixed 2000m relay.

"It is like we never left," said Shaolin. 

"It's amazing. 

"This was our goal, to have a good result in the first competition, and I'm so happy. 

"Hopefully we are going to get even better in the next competitions."

Short track powerhouse South Korea won four gold medals elsewhere in Montreal.

This included victory for Beijing 2022 champion Hwang Dae-heon in the 1500m.

Park Ji-won clinched the first men's 1000m race and his team-mate Gun Woo-kim claimed the second.

South Korea's Gilli Kim was one of two women's 1000m winners, alongside American Kristen Santos-Griswold.

Olympic relay champion Xandra Velzeboer won the women's 500m for The Netherlands and the women's 1500m was claimed by Belgium's Hanne Desmet.

Canada won both the men's 5,000m relay and the women's 3,000m relay.

The next leg of the ISU Short Track World Cup is also due to take place in Montreal, from Friday to next Sunday (October 27 to 29).
