So you want your app/website to work in China
My best best advices are not listed there- Stop using Google CDNs- Stop using Google fonts- Don't put Google Analytics in the header (or don't use it) otherwise will block/delay the browser load the website.Most of the websites just timeout because of those 3 things and make the website imposible to navigate.If you host your website in a normal VPS, without using Google services you will have a quite nice chance that the website loads pretty fast there in China.edit: formatting
