A 24 year old man from Cardiff has been found guilty of murder after beating his girlfriend to death.
Jordan Matthews, of Llandaff, Cardiff, attacked XiXi Bi last August.
Cardiff Crown Court heard how student Xixi Bi, who was just over five feet tall and weighed seven stone, suffered multiple injuries.
Matthews, had admitted manslaughter, but denied murder.
The jury heard student Xixi Bi, 24, suffered massive bruising all over her body and fractures to her jaw and ribs after arguing with Jordan Matthews in the flat they shared in Cardiff, South Wales.
The court heard a weapon similar to a steel rod was used.
Matthews, her boyfriend of 16 months, says he hit Miss Bi believing she had cheated on him and described the argument and her death as a "little hiccup" in a police interview.
During his trial at Cardiff Crown Court, the jury heard Miss Bi had a cardiac arrest as a result of complications from numerous soft tissue injuries, which were caused by dozens of blows, and was rushed to hospital but could not be saved.
Matthews was arrested after Miss Bi was taken to hospital and in a series of police interviews said he could not believe what he had done.
The court heard he met Miss Bi on the dating website Plenty Of Fish and they became a couple after he agreed to help her with university work.
The court heard Xixi Bi grew up in Nanjing, China, but came to the UK to study when she was just 15.
She spoke four languages - and had moved to Oxford as a teenager to further her education.
She was studying at university in Cardiff for a masters degree in international business when she metl for barman Matthews.
The jury heard, after their relationship began, Matthews allegedly began beating Miss Bi and forcing her to miss lectures.
Prosecutor Paul Lewis QC told the jury that Miss Bi would pay the rent, bills and bought Matthews a car.
But the court heard he regularly beat her up and called her "worthless".
Judge Nicola Davies remanded Matthews in custody for sentencing next Tuesday.
