Sorry for the late reply.
You can find the link and picture for Secret of the Linked Cities here:

To choose between Secret of the Linked Cities (about 30 episodes) and Xiao Au Jiang Hu (about 40 episodes) , I would choose Xiao Au Jian Hu.
My top 3 recent wuxia series would be:
Legend of Condor Heroes (China) - great production values
Xiao Au Jiang Hu (China) - excellent fighting
Secret of Linked Cities (China) - Slow start but gets exciting after that
Not bad:
DGSD (China) - Could have been a great show but fumbled unnecessarily
Legend of Book & Sword - Can be slow at times

I generally look for China wuxia. Taiwan wuxia tends to rely on Superstars but are generally draggy and weepy. And avoid Yang Pei Pei productions!
