Inclement weather and empty seats dogged the second day of the Summer Olympic Games in London but did nothing to topple China from its spot at the top of the medals board.
Rain and the threat of hailstorms dampened enthusiasm for many of the day's outdoor events, including skeet shooting and the women's 140-kilometer cycling road race.
British Olympics officials were also forced to hand over tickets to military troops and students after large numbers of empty seats proved an embarrassment in early competition.
But indoors, competing before a large crowd, Guo Wenjun became the second Chinese athlete to win a gold medal for shooting on July 29, taking home the top prize in the women's 10-meter air pistol competition.

Guo came out ahead of France's Celine Goberville and Ukraine's Olena Kostevych. Her victory followed that of her compatriot Yi Siling, who won the first gold medal of the games on July 28, in the 10-meter air rifle competition.
China surprised many spectators on the first day of competition with several medal-winning performances in swimming, a sport usually dominated by the United States and Australia.
Among the winners was Ye Shiwen, who took the gold in the women's 400-meter individual medley with a world-record time of 4:28.43.
Ye swam so fast in some legs of the race that her recorded speed was even faster than that of a gold-medal-winning male swimmer, American Ryan Lochte.
The victory of Ye and a second Chinese swimmer, Sun Yang, was met with celebration in Beijing, where swimming fans like 30-year-old Wu Wanshi expressed hope his country would continue to dominate the sport.
Georgia's Lasha Shavdatuashvili fights with Japan's Masashi Ebinuma (in blue) during their men's 66-kilogram semifinal B judo match on July 29. Shavdatuashvili took home gold.

"No, I never imagined [such a loss]. I worked hard," he said. "I wanted to throw my competitor, but unfortunately, I did not succeed."
