Meaning:

“港” is short for “香港” (xiānggǎng), which refers to “Hong Kong,” and “风” is short for “风格” (fēnggé), which means “style.” The Chinese term “Hong Kong style” is often used by netizens to refer to a popular style of makeup and dressing represented by Hong Kong singers and film stars of the 1980s and 1990s. This retro Hong Kong style focuses on bringing out the natural beauty of Asian women with fluffy hair and accentuated facial features. The overall impression of this style is a lively and natural look.
