Sammy Leung Chi Kin is an actor under TVB, DJ, singer, and host for Commercial Radio Hong Kong.

Leung tried out to become a DJ for Commercial Radio when he was studying at the New Asia College of the Chinese University of Hong Kong.

One of Leung's other radio shows not hosted with Siu Yi is Sammy Moving, co-hosted by Leo Chim, Ah So, Marco, and later Seven Luk (Chan Keung).

In 2009, he partnered with Stephen Chan Chi-wan to host a multimedia show Ten Man Lane.

The poll created an enormous furore, and as a result, CRHK was fined a hefty sum by the government and Leung was suspended from his radio show for two months, during which he could not take up any paid jobs but instead had to attend to classes on media ethics.
