The fourth Multi-specialty Medical Mega Conference was held on 3-4 May 2014 at the Langham Hotel Mongkok. With the conjoint effort of thirty-seven medical societies, around one hundred topics which cover almost all specialties were organized into a comprehensive, interesting and informative program. The most welcome feature of this multispecialty program is that one can not only update on development of your own specialty but also keep abreast on knowledge from other specialties and is very often the most interesting and attractive experience according to many participants. There were 24 themed sessions on various specialty subjects arranged in four parallels over the two days of conference. There is also a special debate session on Public Private Partnership and a plenary session on what contribute a perfect health care system.
