How will it affect the book now that the dad said no to Ji-li's audition?
I think it will affect Ji-li negatively between Ji-li's dad and Ji-li, for example. I think Ji-li will ignore her dad and it will cause a mess somehow in the book. But on the other hand, I think it mainly helped the whole family in a positive way, because it would've been a lot worse if she went and actually got accepted. It would've been bad if she got in because of the political background inspection and that is what would have gone wrong, because they would know they have a bad political background.
I think it doesn't help as much as they think it does, since by four olds they mean they destroy old ideas, old culture, old customs, and old habits. We still use some old customs, culture, etc. in our daily lives, for example religion has been around for thousands of years and lots of people believe that it has helped them live a better life. So it would religions by not celebrating Christmas or Hanukkah or staying up until midnight on new year.
Finally, if most of the shops took down their signs because of the newspaper and radio, does it mean everyone in China agrees to this destroy "four old"?
I think the newspaper and radio must've been a very powerful tools to use in the past to get people to change, since people changed style and signs were removed from shops in a couple of days for banners etc. So I think this must've been a modern technology for them. Although it sounds like most people is in agree with the newspaper and radio, but I think no one is brave enough or anyone in with power wants to fight over it with the dictator.
