In 7 :07, in the dialogue, ‘的’ is missing. It’s not a big problem, but occasionally, some words may be missing in the transcript which causes the inconsistency between what the person said and what was written in the board.
This is a good point and you’re right! But news writing (our news source is Xinhua) tend to omit without affecting the meaning of the sentence. There’re many examples when you browse their website. Thanks for your question.
