How to use your 3de in China?

I am your reader from China,But I cannot load your 3de easily!
It takes a long time before page loaded,can you help me?
you said it will cached the first time load page and will be used offline,
but I found it will not, can you give any question about it? Thanks!

The code that enables offline work is not working with the latest Chrome. I will try to fix it this week. Hopefully 3DE will work better for you after that.

Apologies for the slowness!
