With new rule they force you to purchase a one-way ticket to TPE to commence your next travel.

The work-around is, after you returned from your destination on the ex-TPE ticket, fly to TPE on last coupon but return to HK on the first-segment of next ex-TPE I-class ticket, then have stop-over. Of course this assumes you are frequent traveller of same route, as most I-fares have validity of 3mths or so.
