Based on the Sex Discrimination Ordinance promulgated by the Hong Kong Government in 1995, the author analyzes the legislative background and main content of anti-employment sex discrimination in Hong Kong and evaluates its advantages and disadvantages, attempting to provide a reference for Chinese legislation of current anti-employment sex discrimination.
