This promotion is useless cause it's only restricted to the residents in Hong Kong or Macau. China Airlines' promotion for the Taiwanese working along with the government vouchers beats it like no tomorrow.
China Airlines (CI)
Government Voucher NT$3,600 + airport tax/fees/fuel surcharges
Any short haul destinations from TPE or KHH
