How it's used
This term refers specifically to the traditional style of trousers with a split seam in the crotch area designed for infants to relieve themselves without needing to remove clothing. While once ubiquitous in Hong Kong, it is now rarely seen in urban settings due to the widespread availability of disposable diapers. It carries a strong sense of nostalgia for older generations who grew up during a time when such practical parenting solutions were the norm.

Common mistake
Do not confuse this with regular trousers. Using this term to describe normal pants for adults or older children would be considered very strange or even offensive.
