But your network is not very good. . . Try it. One day, after you download the super movie, you will go to Vipshop. The quality should be much better.

In the meantime, what browser are you using? IE？ 360? Sogou? . . . You should set up a "network speed protection" thing, which includes "download priority", "game priority" and so on. You can set it as "website browsing priority" (it seems to be this,) and it will be ok.
