Yes, especially China. They will be very dangerous, bacause they play at home. But in my opinion China were better four years ago, and this time they won't win gold medal.
yes. reception during athens was just really on point. yang hao was spiking at high efficiecy, zhao ruirui was also really a big offensive threat, and feng kun hits as hard as any hitter from other countries plus she blocks unbelievably (8 blocks against china in the RUS-CHN final)
but i think the home court advantage could make china perform better than what we people expect.
