A warm Welcome to all the new members, @I_M, @Grouchy, @nathsketch (and anyone else I may have missed, know it's not intentional & you of course are welcome)! ^_^
Grouchy:
i want to introduce xianxia/wuxia to friend, but I don't know what to start them off with.
I think Ashes of Love is great for newcomers, since it's relatively fast-paced and easy to understand & follow along. I personally liked Eternal Love better, but I admit it takes a little while to get into it, I'd say after 10+ episodes, so that may discourage them if they're new to such settings.
Another xianxia good for newcomers would probably be Chinese Paladin, but I hesitate to recommend it 'cause modern audience tend to care too much for cgi etc., so I don't know.
As for wuxia, well, my own first wuxia was a movie, not drama, the famous Crouching Tiger, Hidden Dragon, but I'm not sure if this would encourage them to watch more or just ruin all other for them since very little can even begin to compare! :P :'D
I think Blood of Youth is also good for newcomers, full of action and adventure & great visuals.
It's late for me here, so I'm probably forgetting about a lot of other dramas; oh well, any other members having ideas feel free to share them!!!
