From a Chinese point of view, today's highlights have been Yang Wei winning his first ever Olympic gold in gymnastics men's all-around, Zhang Juanjuan beating the Koreans (woot^^) for the archery women's individual title, the first gold in archery for China, the women's team losing by 1 point to Ukraine in sabre team final, and Li Na beating Venus Williams in the quarters! Well probably even more, can't recall now, but the above are all thilling competitions to watch.
For the equestrian events, I gather that Germany has a dream team also. And what's with the Water Cube, even 5th placed contestants are breaking the previous world records!
