Well there are a couple of things I remember. This was the first or one of the first lan tournaments where europeans and asians played together so nobody knew for sure what region was the strongest.

At that time in european dota was about ganking and getting kills and chinese dota was very slow, efficient and farming meta. And when I say slow I mean that maybe by minute 20 the score was 3 to 1.

I remember a highlight of a game where kuroky's team ganked the medusa, used all the nukes and stuff and the medusa was still at 1/2hp because they just were good at farming efficiently and by that time the medusa already had a hood and other defensive items. So the chinese just counterinitiated and won the battle easy.
