A young man fatally bashed in Melbourne's Chinatown precinct was fighting with another teenager over "a lost love" when he had his head repeatedly stomped by a man now charged with murder, a court has heard.

Yarra Valley Grammar student Jeremy Hu, 19, suffered serious injuries when assaulted by four people in La Trobe Place, in central Melbourne, about 10.30pm on April 15, Melbourne Magistrates Court heard on Thursday.
