Hi,
Google translate:
Purchase the license
Be able to buy in China to License.
At the moment we do not have a distributer in China, although you can still purchase through the Ext.NET Store (
http://www.ext.net/store/). One you choose the license you wish to purchase, there should be an option to change the Store language (if it is not already selected).
There are also several payment options specific to China supported in the checkout process.
Hope this helps.
