 Cordero's singing career began after word spread about her singing ability at a newly opened disco in 1985.Offers of recording contracts, movie roles, and stage performances came after a string of hits which began with a tailor-made song written for her by director and songwriter Teddy Robin, titled "Sai Hei".Parts of this song were also used in one of Edison Chen's track 嘥氣 (Waste of breath).
