1993–2005

When Cheng was 16 years old, he participated in a singing contest organised by the Hong Kong television network TVB but dropped out halfway because he felt that he was not ready to be a singer at that time. Later, after he moved back to Hong Kong in his early 20s, he decided to continue his pursuit of a singing career. He signed a contract with the record label PolyGram in 1993 and released his first album in the same year to mixed reviews. He was seen as a newcomer with good potential and managed to win several Best New Artist awards in 1994. Cheng's manager later helped him launch his career in the Taiwanese entertainment industry. In Taiwan, Cheng released several Mandarin albums and acted in some television dramas, but all of them were only moderately successful..^{[citation needed]}

Cheng was noticed by Mediacorp after he portrayed the villain "Jiang Yulang" in the 1999 Taiwanese television series The Legendary Siblings. He returned to Hong Kong and signed a management contract with TVB in the following year and started playing minor roles in some television series produced by the network. In 2004, he played a leading role for the first time in the TVB drama Hard Fate.^[5]

2006–2010

Cheng soared to popularity after portraying "Alan Shum" in the 2006 romantic drama Under the Canopy of Love, for which he also won the TVB Anniversary Award for Best Actor that year. His singing career also gradually improved after the Taiwanese musician Liu Chia-chang composed a single, "Helpless" (無可奈何), for him. In the same year, he also released a Cantonese compilations album and held his very first mini concert. Niki Chow, Raymond Lam and Miriam Yeung were among the guest singers who appeared at his concert.^{[citation needed]}

Cheng had another critical breakthrough role in the 2007 crime drama The Ultimate Crime Fighter, in which he played the villain "Aaren Chong" and earned glowing reviews for his performance. In the 2008 thriller-suspense drama Last One Standing, his portrayal of the ex-convict "Sing Hei" earned him further critical acclaim and widespread praise from viewers. He was also one of the top five nominees for the TVB Anniversary Award for Best Actor in 2008, but the award went to the veteran TVB actor Ha Yu.

In 2010 Cheng took up the role of 8th Prince in Startling by Each Step (Bu Bu Jing Xin) which later brought his career to greater heights and has since gained him recognition in China.^{[citation needed]}
