Cheung Ka-long wins second Asian fencing gold
Hong Kong fencer and world number one Cheung Ka-long on Sunday won the Asian Championships in Seoul, his second regional title.  Cheung, an Olympic gold medallist, took home the victory in the men's individual foil event after beating China's Mo Ziwei 15-6.  The Hong Kong athlete had won the 2016 Asian Championships in Wuxi.  His teammate, Ryan Choi, was defeated by the eventual silver medallist in a close semifinal match earlier in the day.  Choi, along with Chinese fencer Wu Bin, who's lost to Cheung, both claimed bronze at the regional event, as there's no bronze medal match.  Another Hong Kong fencer, Vivian Kong, clinched victory in the women's epee in Seoul on Friday.
