Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 2 blocking CSS resources. This causes a delay in rendering your page.
Optimize CSS Delivery of the following:
http://stc.v3.news.zing.vn/wap/css/mobile_2.33.css
https://fonts.googleapis.com/css?family=Noto+Sans|…t=latin-ext,vietnamese
Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
http://pagead2.googlesyndication.com/pagead/show_ads.js (60 minutes)
https://pagead2.googlesyndication.com/pagead/osd.js (60 minutes)
http://www.google-analytics.com/analytics.js (2 hours)
Minify JavaScript

Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
Minify JavaScript for the following resources to reduce their size by 1.8KiB (28% reduction).
Minifying https://cdn1.mobfox.com/javascriptsdk/ad_sdk.js?cb…de%20end%20--%3E%0D%0A could save 1.8KiB (28% reduction) after compression.
