If you talk to Hui Chao, he will show you the Quest Reset list.
If you want to reset one of these quests, obtain the appropriate Secrets of Time license. If you have a Secrets of Time license in your inventory, the listing for that quest will not be shadowed (lit up) in the Quest Reset list. Then simply select it and click the Quest Reset button.
You can, but no longer have to, visit Hui Chao to reset quest chains. You can simply reset the quests by clicking the Reset button in the Quest Log from wherever you are.
