Although Mạnh Đình attended voice classes in Vietnam, he only sang as an amateur in local shows and in the petroleum company of which he was an employee. In fact, Mạnh Đình didn't even think that someday he would pursue a singing career. But, like many turns in life, fate and serendipity led him to enter and won the 1993 Golden Voice Award. The contest was Duy Khanh's brainchild and one of the judges happened to be Truc Ho, musical director of Asia Productions. He was contacted by Asia's staff and was offered an exclusive contract.

Mạnh Đình literally fell into the business and found success where many have failed. There have been many contest winners but very few ever find success professionally. Since he signed with Asia, Mạnh Đình has appeared in all of their music videos. Although he is considered a late bloomer, Mạnh Đình has established quite a name for himself. His duets with Như Quỳnh on Asia's videos have received many accolades from the fans.

To date, Mạnh Đình has been the feature singer on five Asia CDs and has collaborated with other Asia's artists on several CDs and music videos. His most memorable and successful performance is his rendition of the song, Chuyen Dan Thien Ly. Although many people have typecasted Mạnh Đình as a singer of que huong music, he has found success in singing romantic ballads as well as other types of music. Read more on Last.fm.
