Last month, Hieu won a stunning victory in the WBC Muay Thai minimumweight match against Thai boxer Pornthip Khamthongphanow (the world's No.7).

The victory not only gave Hieu her first professional Muay Thai title but also lifted her from 5th place to 1st in the world ranking and made her the highest-ranked Vietnamese boxer in the history of WBC Muay Thai.
