Try another browser or another link for download, I can't say what's the problem is for you.
谢谢，我试了很多，pc里面只有压缩的是正常的，没有别的意思，我只是想知道压缩版内容上是否有不同，还有画质方面差别会很大吗？
It seems like it's the issue with your firewall or something, everything that is not compressed is on external links, one of three should work. And there is no difference in normal and compressed versions content wise.
