Miss Hong Kong Pageant
She won the 1979 Miss Hong Kong Pageant and was also elected "Miss Photogenic." She represented Hong Kong in Miss Universe 1979 in Perth, Western Australia, where she went unplaced but ranked a very respectable 21st place in the preliminary swimsuit competition. Olivia created a controversy when she joined ATV (the arch-rival of TVB, the organiser of the Miss Hong Kong pageant) immediately after crowning her successor in 1980. This incident embarrassed TVB so much that in 1981, TVB decided to sign 1.5-year contracts with all Miss Hong Kong winners so that they had to stay with TVB for at least 6 months after their reign was over.
