A: I like fencing very much.  And the Chinese fencing team is great. But it's a pity that they haven't won a gold medal in over 20 years.
B: When was the last time they won the goldmedal?
A: The 1984 games in Los Angeles. That was China's first gold medal in fencing. I hope that China will be awarded a gold medal soon.
