Without the written word, it's a bit difficult for me to translate any word that I don't understand. Anyway, I managed to catch most of it. So, it turned out to be a last-minute decision to replace Cai Yun with Zhang Nan when originally they had wanted Cai Yun with Fu Haifeng for their experience on big occasions as they later realized the latter two, due to not having played together for quite some time, had fallen rather low in world ranking and would not be able to play MD2 as fielding CY/FHF , WR47 at the time, would require them leapfrogging several other CHN MD pairs, particulary Chai Biao/Hong Wei at WR15, and leave CHN with very few other options - that's what Zhang Jun explained. Even Fu Haifeng said he was taken aback twice by the changes, first when he was told to partner Cai Yun , then later that it would be Zhang Nan instead who himself was equally surprised by the sudden decision to pair him up with Fu Haifeng. By the way, the narrator said Cai Yun wasn't at the training ground that day but resting in his room (probably not fully recovered yet from his minor injury incurred at the recent CHN Masters ). That's my understanding of the gist of the matter.
