I can't tell if this is recent or old, but you can download them without signing up for anything, it's just complicated. So, even if you have it already, here's how to dowload from rayfile(which will help you with other creators who upload there too):
-click the rayfile link: http://www.rayfile.com/zh-cn/files/248469eb-020e-11e0-af30-0015c55db73d/
-on the page that opens ignore the big blue buttons and click the top one of the two paler blue small buttons with a green down arrow on it
-an advert will open in a new page/tab, let it load fully then go back to the previous page and click the pale blue button again, it'll start the download. If you take to long to click the pale blue button again, it'll open another ad, just ignore it and click the pale blue button again.
It sounds incredibly confusing and it's a bit easier if you use google chrome and let it auto-translate the pages, but it's useful to know as a lot of creators using the sina.com blogs seem to use rayfile for their uploads.
