Here is the page for Chinese (now with an updated link! :P):
As per yesterday’s announcement, we are beginning to publish the Facebook pages for the other languages on LingQ. I encourage everyone who is studying Chinese to take part in the page and contribute in the many different ways possible, from saying “Hello!” on the wall, posting links to websites that you have found helpful, or adding pictures or videos that you find interesting.
We hope that you all find these pages useful in meeting fellow language learners. If you like what you see then please tell your friends to check it out and “Like” it. I know I will
