Try relog and quit all quests you have or try make all quests. There should be a pop-up message for the quest to go Hefei. Check if you quit from your master. You must quit the master before you recieve the quest.
Visit your clan master. You will need a lot of clan contribution thought to progress. Hope this helps.
