In 1982, he passed the training courses of television channel TVB. Due to his boyish looks, TVB cast him as host of a children's programme, "430 Space Shuttle". Leung enjoyed comedies during his television years; it was for these he became well known. So, in the 1980s, he was named as one of "TVB's Five Tigers" (their five up-and-coming male TV stars) along with Andy Lau, Felix Wong, Michael Miu and Kent Tong. Leung starred in the highly successful "Police Cadet" TV serial in 1984 (later named "Police Cadet 84" to distinguish it from subsequent sequels).
