Congrats to my boy @rextso on an amazing fight tonight! He took down Hirofumi Mukai with a vicious body shot KO in the 8th round to retain his WBO International, WBO Asia Pacific and WBC Asia titles to extend his record to 21-0 13KO's! Hold that Hong Kong flag high brother! We are so proud of you!!!! #hongkongboxing #boxing #WBO #WBC #defboxing
